No, not at all -- it sounded like you were saying the developers and users of such things were being naive, but maybe I'm mistaken. To give an example of what I was saying, if I was contributing to Postgres, it would be because I want to help make a good database and fix bugs. I wouldn't do it because I had a chip on my shoulder about Oracle, even if I did have that (I don't). But that's just me. OTOH I believe Oracle even offers some level of support for Postgres.
