Amazing how still many of those developers post things like "Hey Elon Musk, something broke, please help us" rather than "Hey all, Elon Musk once again fucked with the system we're paying $42,000 / month to use, and there is nobody at Twitter we can even talk to".
If you're willing to pay 42k then you're probably running a business and need to maintain a relationship with Twitter. Taking shots at their owner, regardless of how you feel about them, probably won't give you the outcome you want.
It's easy to do the right thing when you have nothing to lose. It's a different story when your job is on the line.
They would have to be a business relying on Twitter for an important function. A lot of developers are in a difficult position, especially if they decided to use social media sign-ins. They need time to develop an alternative and to allow users to change their login method. But many users won't care and will ultimately just stop using the service. The developer may decide to keep paying as opposed to losing a part of their user base.
They've had this mostly locked out for a while. Certain direct links you could click but that's about it. The links they sent in their emails didn't work without a login.
From these collapses of Twitter API, I learned that API developer must work standing on free and open mind for other developers using the API, even if he/she joins commercial enterprise.
