Re: One thing people tend to forget about FOSS.
"By it's very nature, FOSS will be around as close to forever as makes no nevermind. Corporate closed source software, on the other hand, is just as ephemeral as the company in question."
Not so sure about that. There's plenty of FOSS that has withered on the vine. There are usually alternatives, but that's not always ideal for those used to whatever app stopped being supported due to lack of maintainers.
I used to like klibido for Usenet binary downloads. Unless going commandline, it was about the only GUI based option at the time. Pan didn't really do binaries back then. Nowadays, Pan is the only option and even that's pretty precarious. There was a long drought when the one and only maintainer really wasn't doing anything with it due to lack of time. Even now, since a major re-write and update, there's still really only one prime maintainer and a couple others who help out with minor bugfixes. I'm not sure when I last saw an update.
Now, you might say that Usenet is a niche thing nowadays, but it's actually still quite lively, but FOSS options to access it, at least in *nix land, are few and far between.
There's still the likes of Thunderbird and Evolution, but news always feels like the unloved step-brother and not really looked after properly like the mail client parts.
