Why wasn't there a Twitter protest when they increased API prices?

I think the context was rather different. The reddit thing was slightly out of the blue; lots of basically happy Redditors and then suddenly, chaos.

Twitter, by contrast, well, there's a reason that Twitter users affectionately called old-Twitter the hellsite; there's always been a slightly sadomasochistic relationship there. And bear in mind that this happened as part of a collection of stupid decisions by new management, and rather late in that series. The attitude, by the time it happened, was far more "well, screw this, then" than fight-the-power; Twitter was kinda ruined _anyway_. For people who cared about Twitter-as-community, it was, I think, just part of the decline and fall.

Personally, I'd already left twitter when it happened, though if I hadn't left over some earlier nonsense by Naughty Old Mr Car I'd certainly have left over the API (the first-party app is frankly unusable).

There's also, I think, a question of what can reasonably be achieved. Twitter is not being run rationally; you can't expect that it will respond in a normal way to negative consequences to its actions, because, well, I mean, see all changes over the last 9 months or so. Reddit, by contrast, is a fairly normal company with normal investors and a board and everything; if it perceives that its actions are hurting it it might reconsider.

There was - a major one.

But Twitter killed ALL the third party apps beforehand.

Meanwhile the fact that Twitter's valuation has dropped so badly since Elon brought it shows the effect these individual protests had.

I recall a lot of protest and negative feedback. I was supporting an open-source API library for years and stopped. They just ignored everyone.
