I have never seen a post by lantus ever before, so I genuinely come into this with no biases. I also have no public opinion on whether he should or should not disclose the sources to the software, so throw that out the window, too.
That being said, I know what Sir Auros is saying - that lantus should try to be a bit more open-minded about suggestions made by his userbase. If someone asks why he doesn't release the sources, I'd take that to be a genuine inquiry. It looks as though lantus interpreted that as a gauntlet being thrown.
While I do think it would be more appropriate that lantus be a bit more polite to loyal users of his software who are only trying to learn more about it, it's also his choice how he wants to act. If Joe Developer wants to release great software and tell everyone they suck, who can tell them to act any differently?
Anyway, Sir Auros, try not to let it bother you in the future. It's tough to say someone brings the scene down when they put out software. Mouthing off keeps them from being a god among men; it doesn't cause anyone any harm.
