It's because nobody actually has trouble understanding what "free" means in these contexts except the same small percentage of morons one can get to say any dumb thing one wishes to find someone saying, and people pretending not to understand it on Internet forums to passive-aggressively make a very stupid point. Everyone else gets it. You're not preaching some great message to the sheeple, you're just making noise.
