People hate BAT for reasons, but the idea of controlling the ad stream at the software level is a winning one to me. I can't think of any other platform where ads were given such free reign. Could you imagine watching TV, then a commercial comes on that either a) crashes the tv, or b) changes the channel multiple times so you can't get back, or c) installs malware onto the tv, or d) clones itself 20 times over the content you were watching, or any other fun stuff web ads have been known to do.
