It's funny, Elon's trying to figure out ways to increase revenue, but he basically cut off all revenue from developers.
Yes, I know this is all about increasing advertising revenue. But there's ways to do that without banning third party apps. They could change the API so that third party apps have to show ads, and any revenue from that goes to Twitter. They can also have different tiers, with a more expensive one with no ads.
Or maybe there isn't anyone left working for Twitter that knows how to change the APIs.
I mean... all the skilled API coders are probably all gone since November.
The only ones left working there are the janitors.... umm wait....
