not sure the intent really is to make fun of people. I read it as (light) criticism, which isn't the same thing, and which should be allowed by all means preferrably without people getting all politically correct about it. Imo.

Apart from that: I'm no designer but some of these logos look hideous to me. Though I also think some of them are just meant to be like that, as a f*k you statement: "it's about the content, not about the logo". Which is prefectly understandable: ever had to come up with a decent original logo? That can take days which could as well be spent programing for instance.
