>But Twitter's repeated, bizarre, and unexplained API limitations hobbled the system more times than I can count. They'd suddenly suspend one for "API abuse", I'd get it manually reviewed and they'd release it.. only to have 10 suspended the next day. I even started asking followers to tag @TwitterSupport on our behalf and zero progress.

Fundamentally that's the result of a toxic, lazy engineering culture that thinks the solution to heavy load is to punish users rather than improving the system. Whoever was in tech leadership positions there at the time should be ashamed of themselves.
