That twitter story isn't anything unique to OpenAI or Google, it's just classic "big public corp vs private startup" culture. Once you have to worry about the SEC, shareholders, antitrust, regulations, lawsuits, etc. it's very, very difficult to avoid turning into "big corp" culture.

Sama, and any other founder, will always have a difficult fight against bureaucracy, and once you let a little bit in, the bureaucracy's sole purpose becomes to grow itself.
