Maybe if you took a step back, you wouldn't feel so irritated. You could be stuck working on an AS400.
As I said, not that I think it matters. But "no one pays for open source" frequently just isn't correct these days.
I understand it's paid for one way or the other, but to use it, it is free. I'm comparing it to before, if you wanted to try a Microsoft product or something, you had to buy it and once you broke the seal, you owned it* (or the little plastic disk and box).
Also, if the OP was a maintainer, I can see where he would get frustrated. I assume he was just some overzealous user.
Anyway, the fact that open source even exists is probably the best thing to happen to computing since it's invention (and I'm not even much of an open source user).
*No refunds.
I remember the days of batch creating UPC barcodes on an AS400
