A better response to criticism would be to try and learn why people think they are terrible instead of looking for a reason to feel insulted. Whether OP is making fun or not isn't even important. Let him have a go if he wants. Whatever his motivation is, he's got a point. The logos are terrible. These aren't necessarily subjective judgments; there is such a thing as best practices for logo design. Remember what a logo is for. Hint, it isn't to entertain the programmers or designers. It is meant to be a visual cue to help people recognize your group/company/club/whatever. It should be simple and concise among other things.

> It's not as if they needed to market them.

I disagree, IMO a wider userbase is usually a good thing for GNU/Open Source projects, for the community, and for the software/services industry as a whole.

>Yesterday there was this thread about the "three = 1" in the linux kernel source code,

Yes, and that thread generated a reasonable discussion about programming. How is that a bad thing? Do you think someone will stop using ext4 or Linux because of a questionable variable name in a rarely used bit of filesystem code?
