It's not for the satisfaction. It's just that I spent more or less my whole teenage years (and years after) playing this game.
Now, I can't say for sure I haven't behaved disrespectfully in the past, but I kept in mind that they are doing it for free, that this community and the game is not about monetary profit.
It's the profit of making something, playing something that's worth it. Sure, this community has trolls. But somehow they are part of it and I love the community as a whole, I also met few guys IRL, I'm sure I will meet some more.
Nowadays I am not playing the game, as my signature states, I'm stuck at WT. But Movie Battles has become the largest part of my gaming life, so I try to contribute with something, even if it means to defend devs.
I just disagree, it's Lou's decision what he might do with his free time. And his free time gave something new to the forums. It deserves at least pat on the back.
