If you don't want to get flamed, don't post a flaming OP.
You would think this is a sensible rule to live by.
Come to think of it, no dogpiling actually happened until somebody said "I wonder if this will end up like killer studio technomanga". Saying that is antagonistic and should be called out, because the OP wasn't nearly as stupid as what happened in those other threads, and comparing his post to that really is what started the negativity/super sarcasm/memeification.
It was mostly actual refutation of the OP's complaints (OCR still doing free music, selling out is an exaggeration, etc.) up until that post.
