There's no reason for them not to; I'm not sure why you would expect them to avoid doing so, if it would help them spy on communications. It's not like it's terribly risky for them; they can stick some exit nodes on some racks in a couple of data centers, with splitters that records all of the traffic coming out, and no one would be the wiser. Or they can just find existing exit nodes, and ask the data centers to install splitters for them. Exit nodes and relay nodes are not secret, so specifically targetting them for analysis would be pretty easy.
