>It's called free because it's "given without charge"

It's not given without charge, because the taxpayer was charged. If my friend buys my lunch because I left my wallet at home, or it was more expensive than I thought, I don't say "oh wow, free lunch!" I acknowledge that the lunch was paid for by someone else. I certainly wouldn't go around telling people I got free lunch that day. That's a surefire way to make sure nobody helps me out again.
