I don't have a problem with anyone making money if one can. Good for him I say (the opposite was not my intention in the original comment), he found a way to make some money while doing open source software.
I don't think you understand. This isn't "a way to make some money while doing open source software"; if anything, he's probably losing money on this.
The man is taking time off his job to do something he loves for a community which he's put a lot of time into, and that's something anyone should respect.
