Yep. Much of this is sentimental. I associate Java with Sun, which doesn't have the same aura of evil as MSFT or Oracle. Thus I hate Java mostly based on its technical merits and the thousands of hours I've wasted with it.

While this is sentimental, as in it can't be exhaustively explained by logic and known facts, I still think it's somewhat rational. Fool me once etc.

The newer generations probably don't really grasp what MSFT pulled on OSS, developers and computing in general to make it the monopoly it is. It's possible that it has changed course, but I'll probably never trust it has.
