Yeah I think this is the thing that kills it.
First: Twitter is officially a dead zone for any artists. If you're following a bunch of art pages, you're gonna hit that limit in probably under a half hour. Not to mention the artists' perspective: why utilize a platform that will actively bar your audience from seeing your art just because they saw someone else's first.
Second: Twitter just fucking obliterated its ad revenue. Say I'm an advertiser, why the hell would I pay for ad space on a website that is likely not going to be seen by most users because they hit their limit. It's like paying for a billboard on a highway that's shut down. While obviously a move to push people to pay for the subscription I can't imagine that would be worth losing out on that much ad revenue.
Third: While this has already been declining since Musks' takeover, Twitter has now become possibly the worst outlet for PR and News outlets. One of the bigger draws for Twitter was it was a big platform where celebrities, media outlets, etc would post announcements, breaking news, etc. During major events Twitter was the place to be since you could see journalists posting updates on developing situations in real time, often even with pictures and videos from the scene (the US Capitol Riots in 2021 are one of the best examples of this). With a limit on views, Twitter is now the worst place to follow these scenarios as you'll likely be locked out of any updates within minutes, and the clowns who paid for premium will probably be locked out in an hour in these kinds of scenarios. The only real winner in this case is likely news outlets as the most convenient place to follow breaking and developing stories will be on their own website.
I genuinely can't think of any end user who benefits from this change.
