I don't see the relevance. All I'm getting is a lot of criticism of some comment Scalia once made which seems to have nothing to do with whether things should be called entitlements.

Further, if that was somehow your point, bear in mind that "everyone" in this context is pretty clearly something like "the vast majority". I could find traces of evidence of people trying to redefine the term, sure, but no evidence they're being particularly successful. Even the NYT calls them entitlements with no apparent irony. Call them mainstream or call them leftist, either way, it's evidence on my side.
