Seems you are getting similar treatment as I did in the past for posting relevant XKCDs. I'm guessing it's because you aren't adding much value to the conversation, but could be some folks hate XKCD too I guess.
Not a downvoter, but it doesn't quite work. Google isn't against open-source. It's somewhat related, but not exactly.
I didn't see that XKCD is being specifically about open source. That said, the one I posted a few months ago was spot on and yet it was downvoted to death within a few hours, so I don't think it really matters how perfect the fitting is.
