The overly generous image/video generation was a product of their excess compute. No point in letting it sit idle while you build up your infrastructure. But you were getting far more than what you paid for. Now your quota more accurately reflects the cost to create it (even still its generous compared to api costs) but everyone has their expectations set based on the subsidized access. Perhaps giving away too much is counter productive because users will revolt once the quotas are changed to better reflect reality.

What media do you even generate every day?

And their code solution is now Cursor, which has very generous limits.

You pay Twitter money to generate thirty videos per day?
