Meme is being used as "better than this" comparative.
Which, considering what the 'good' 'untumblrized' image is, I whole-heartedly agree with.

I'll take a chaingun goddess over a thot any day of the week!

Same thing happened with the Virgin v Chad meme, it was originally poking fun at how obsessed 4channers were over the impossibly unrealistic ideal of the "chad", then it turned to Virgin=bad, Chad=good.
