Instead of a flat number to limit tweets across the board, there should have been instead a comprehensive useage-percentage based on the individual using the app, and how much data they use per day.
The average user should see little-to-no change apart from increased targeted advertisements, but for those who spend their entire lives on twitter, or if they use twitter for business, they have to pay. And if they go beyond THAT limit, they have to pay even more. So on and so forth, cut deals for business accounts running multiple handles.
For third party apps that scrape data, make them pay as well - which will immediately draw comparisons to Reddit, but Twitter is an infinitely more valuable resource in comparison to Reddit (relatively), and addicts have yet to fully migrate on ANY of the numerous alternatives that have popped up before/since Musk took over, simply because "it's not twitter".
What I'm getting at is, let the VTubers ego-search - for a price. VTweeters should pay double.
