There are likely a ton of tools that are using the Twitter API in ways that helps Twitter and almost all of them are going to be locked out because there's no way they can afford $42,000/mo.
I'm on a slack channel of (mostly former by now) developers using the Twitter API, and the general feeling is that Twitter is dead for most. A few lucky ones are able to afford the new 42k/m price point, and everyone else has been kicked out without any respect by Twitter, and won't be coming back.
It's not worth their time or money, I'd bet that that API integration helps Twitter more than it helps MS.
