"How can an MVNO manage to carry out the billing admin cheaper than the network owner?"
My assumption was that they simply charge less margin than the owner, who is seen as worth paying a premium for by some customers.

"This gentleman is being naive if he thinks that the Apple store works differently from any brick and mortar store."
I would not be surprised if people don't treat movies they have bought on the Apple store, as being in "their cloud", just like many other stored things, which don't disappear on a whim.
"Why would I want to pay THEM for when there's no mobile signal if I were lucky enough to get wifi instead?"
I was in the same position as you, wifi calling is new to me. But I believe the point is that it goes over Wifi to 3, who route the call via usual methods. That's why you pay them.
As you say, you are free to use Skype or WhatsApp if your contacts have those too, and these days probably most people do. Wifi calling has come a bit too late IMHO.
"because energy applied to them just makes them heavier"
Yes, and time slows down. I am fond of the analogy/model where things are always travelling through spacetime, at the speed of light. ie. 1sec/sec for an object at rest in space, is lightspeed in the time dimension.
The faster you go through the non-time dimensions, the slower you go through time because some of your lightspeed velocity is taken away from the time dimension and used to move you through space.
When you are going through space at lightspeed, time stops because you've used all your lightspeed for space travel rather than time travel. As I believe is said to be the case for photons.
Easy to imagine as a 2-dimensional plane with time on one axis and space on the other.
Not quite.
Plus you have mixed up Dark Matter and Dark Energy.
Dark Matter explains the behaviour (gravitational) and morphology of the universe and things in it, ie. Galaxies and Galaxy Clusters.
It is hypothesised because it's the simplest explanation that is consistent with other observations. It's not really a circular argument because the stuff that's hypothesised is "matter that we can't see but which interacts only or mainly via Gravity". Nothing wrong with that. We don't know much else about it but lots of work is ongoing to narrow down the options.
More complex hypotheses may be possible too but usually it works to go with the simplest one that is consistent.
Dark Energy on the other hand is much more like the sky pixies you mention. It's a placeholder for an explanation for why the expansion of the universe appears to be increasing.
If and when someone comes up with a better explanation that is consistent with other observations and theory, then great, it will be replaced or explained in more detail. That doesn't mean we shouldn't have such a word.
Newtonian Gravity was much the same. What is Gravity? A force that makes things attract each other. Why do things attract each other? Because of Gravity.
I've never understood these complaints about the UI. Maybe because I wasn't a Photoshop user first?
How is it complicated? Seriously, is there any site where someone has reviewed the UI and listed out specific items? I am interested to know what I am missing out on.
The 13A fuse is not because the TV is expected to draw 13A, it's because the TV is NOT expected to draw 13A.
Most short circuits to earth or wherever will blow a 13A fuse pretty much as quick as a 5A fuse (no I haven't done the calculations) so it does the job even if 5A is theoretically safer.
Actually, it doesn't. It says that pages won't stick around in your browser's history, cookie store, or search history after you've closed all incognito tabs. It then warns you that this doesn't protect you from your employer, ISP, or the websites themselves, naturally.
But it doesn't say that Google/Chrome will record your history when incognito.
Yes there was, there was Sinclair's earlier effort for one, the Mk14, which was similarly priced and much more primitive, and there were home and business machines from the US, some of which may have been better but were much more expensive and less suited for home geekery.
Actually copyright "began impinging directly on the public mind" because technology enabled both creators to create and consumers to copy, from home taping through to computer files.
It works both ways and it's still valid. I have put a deal of effort into astrophotography over the years, largely due to technology making it possible, and I'd not like for a freeloader to use my work for their own benefit without at least credit. I have been asked, and granted, permission to use certain of these photos over the years and never felt that I had to say no. Some educational publishers gave me a fee although the admin involved means I now granted them to use it free of charge. But that's not to say I would do the same for any organisation, depending on the intended use.
You say Copyright is bad law because it's difficult to enforce. So is enforcement of not stealing bicycles in London. But it's not bad law that stealing bikes is illegal.
Uptime is understandable, but why would they ever lose small amounts of data? The provided should have proper backup and redundancy in place which means they never lose anything, ever (subject to a certain amount of downtime), or they lose everything when they go out of business. How is there any in-between? Sounds like pure marketing to me.
We do have an alternative but the problem is not that we use the spinning rock as a base and it drifts, it's that we use a more regular source as a base, and it doesn't drift, therefore getting out of sync with the spinning rock, so if left uncorrected the point of highest sun wouldn't be at 12:00, eventually it would be sunny in the night time, and so on.
Pluto wasn't demoted, strictly speaking, because it was too small. It was because other bodies had been found of similar size, and they didn't want to open the floodgates.
Actually the only criterion for planethood that Pluto doesn't fulfil, is that it has not "cleared it's neighbouring region".
I don't think it's as simple as marketing guys calling something fibre when it's not.
In the old days it was copper all the way to the exchange (or aluminium I guess). Then FTTC came along and they needed a way to describe it.
There is some fibre in there, where there wasn't before. So they call it Fibre, and mostly it's a couple of times faster than ADSL. I don't recall many people complaining. Then along came FTTP which is more fibre and even faster. So now the old fibre should be called partial fibre or something perhaps?
