Oracle is exactly who sprang to mind. Throughout my history as a software developer, even Microsoft has had a ton of interest in being involved in the community. Yes, they've wanted to extinguish much of it, when it didn't align with their financial goals... but they were always interested in being part of the "software development conversation". Oracle on the other hand has never extended an olive branch. They're quite happy existing on their own proprietary island. A great reminder that, "they don't want ot play in the pool with you, they want to own the whole pool and charge you to swim in it".
