/pedant: it is, actually. Definition is "ready to face danger or pain". "Brave" is mostly used approvingly, but it's also completely proper in sentences like "He decided the app should be IE-only, which was a brave move but one he felt was justified by ..."
Similarly with "daring" -- you often hear of "daring robberies" and the like.
Sorry, you don't get to be all prescriptivist in telling someone what "brave" doesn't mean, then suddenly produce a descriptivist defence when you're called on it; they're incompatible.
It's sometimes funny that people take this position.
Personally, I don't give 2 hoots if companies want to sell my information to each other. Good on them. I lose nothing by them doing it. Couldn't care less. (As long as it's stated in T&C that they are doing it).
It's especially ironic, since people moan at the music companies, saying that downloading music illegally isn't theft, since you haven't deprived them of anything.
I'd rather a company like Facebook err on the side of innovation.
