I do think he deserves ridicule, but not for that. He stood up for the ideals of free, anonymous speech. He believed in it. But he eventually buckled under the weight of it. He was a hero for holding out as long as he did, but all heroes fall. What he's become now is worthy of ridicule.
1. it's impossible to satisfy this poster and their parent at the same time.

If 4chan was a traditional for profit business, I would agree with you. That's not what 4chan is, though. Moot's given talks on the value of anonymous conversation. His view was that it's the only way to have truly free speech, free of racial, social or sexual bias. Where ideas and ideas alone are exchanged. I imagine his opinion on that has changed over the years. That's fine. But in the process, he alienated the very people he created the site for, his core audience.
