The funding runs out and they have to try and monetize their users somehow. Or the tech company goes public and now they have to try and produce increasing dividends for their investors every quarter.

If I remember right, Reddit’s official reason for the api pricing change was continuous scraping of content for AI training data, putting more load on the server. There’s probably some truth to that. Twitter and reddit also have very large user bases, which requires more resources.

Elon Musk being in the driver’s seat of twitter probably doesn’t help either.
