If Twitter was planning on re-releasing their API after shutting it down last month their communication has been completely incompetent.
Who would trust them enough to build a product based on an API with a record of shutting down without notice?
Honestly, I doubt tweetbot and similar apps will return.
This is is going to destroy Twitter's developer ecosystem in the short/medium-term.
$100 / month for 50k POSTs sounds reasonable-ish, until you realize it's limited to 3k tweets per user / month and most helpful bots have a single user.
Take ChatGPTBot, for example, an OSS bot which I run that has over 100k followers. It's very simple but super helpful; mention the bot with a prompt and it responds with a response from ChatGPT. Each response uses 3 POSTS (1 image, 1 alt text, 1 tweet), and remember it's only 3k tweets per user / month.
So ChatGPTBot for $100 / month could effectively only respond to *1 tweet per hour*.
That's insane for the price and will kill all open source innovation around Twitter.
I hope this type of use case gets addressed soon, but imho the damage to trust in Twitter's developer community is already done either way.
