It still is. However, we still have semantic errors which mislead people. I don't "have the internet on my iphone," I do allow random people on the internet to send stuff to a computer I neither really control nor understand but to which I trust an awful lot of personal information. I do not "have" this app, I HAVE installed a random bit of code, from people I don't know, with whom I have no discernible relationship, on a computer with lots of personal data on it.
Its good that people share these stories. The more publicity this sort of thing gets, the more people understand that the more (even transient) information (such as whereabouts) is stored and shared with code of unknown origin, strangers, government, corporations, cloud storage organisations, the more dangerous it is to you personally. Stop contributing to these infrastructures.
My take on the matter is simply don't do it. Don't bother trying to secure a zillion and one apps, just stop sharing where you run, cycle, walk, what you had for lunch and where it was. No-one needs to know that. My weather app doesn't need my location. I can use privacy mode in the browser and give it a postcode of a major town nearby - it doesn't need to know I'm down at the bottom of my garden. That URL gets stored in the local history, not synced up to some cloud, not even for Firefox.
Give me rsync over ssh over a vpn to my machine at home for "cloud," and I'll be happy. OneDrive I do not want even if it did have unlimited free storage. Application-level clouds are even worse. Per-application storage protocols? No thanks.
If I want to socialise and share with friends, I'll schedule some time to be with them. "You're my friend, but I'm only going to broadcast my information to you, not spend time listening to you" doesn't cut it, not even if the broadcast is two-way. Why have have something as inhuman as a computer mediate social activity? Go back to the clubhouse or pub or invite people home and regale them of stories of the close calls you had with a bus on your bike ride. That is how you build friendships - not by clicking "like" or sending them GPS coordinates of where you ride or where you had lunch.
Stop sharing with corporates, software and devices and start sharing directly with people you know. That is how you develop appropriate trust boundaries.
