I guess for now... unless someone wants to literally scrape Twitter until they figure out how to ban that as well. I don't think it is worth the time developing for Twitter anymore. These apps brought users to Twitter and now they want to take them away.
This is why one should always be wary of platform risk, as a startup founder. While it might be profitable in the short term to use someone else's platform, it always comes with the implicit risk of being shut down on a whim.
For growing an audience, email is platform with the lowest risk.
The solution is to give users a toolkit for making 'apps'. They enter their username and install the generated app which does a thing. When they run the app, enter their password. 1P apps only.
Someone at Twitter cracked time travel?
