I guess it also helps that I've never used Twitter, so I've literally lost nothing.
Eh... if you have much appreciation for artwork, you're probably in the process of losing things. If there's one actually bad thing about twitter repeatedly shanking itself in the dick, it's that unfortunately a
lot of modern professional creative work has been reliant on it for networking and business (commissions, etc.), and its problems are causing
them problems.
I've yet to see an artist or other sort of creator
happy about that reliance, and basically all of them have been trying to diversify for years, but the flat fact is that the numbers they need (access, visibility for stuff like job applications or whatev', and so on) has been on Twitter and nothing else has it. This shit's hurting them and going to hurt them worse, through no particular fault of their own, and that sucks pretty hard.
There's apparently other fields with a similar issue, for that matter. It may be something of an object lesson about the potential problems with that kind of reliance, but, well... the actual creators involved don't really have enough weight to make a difference on that front. They kinda' have to go where the relevant people are, and twitter's been where that is. The object lesson to be learned is sometimes life's just gon' fuck you and everything you love regardless of what you do, which isn't exactly a helpful lesson.
... the NSFW commentary's particularly relevant, though. Twitter was one of the very few major platforms that still allowed even a modicum of NSFW content, and it going in the shitter is apparently hitting NSFW artists and various sex workers/performers and whatnot
particularly hard, which is unfortunate on a pile of levels.
