Why does it seem it's only Twitter with this problem? (or at least the most frequent and public).
Twitter "hoses" developers all the time who were making money based on apps supporting Twitter. They "hose" the developer because Twitter would rather make that money instead of allowing others to, yet they then fail to capitalize on the vacuum they just created.
Over time, it's made Twitter a seemingly very unattractive platform to try to dev against. Twitter doesn't make much in terms of earnings on their own, it seems it would be in their best interest to allow an ecosystem around their platform.
