Right. Another thing is that it's not clear whether they're inserting an advertisement into the conversation in a way that's visible to the other person, or if they're only trying to bring up on-screen help for the local user. The former seems much, much more intrusive than the latter. I'd still like the option to turn off either of them, but I don't really consider Clippy-esque eagerness to be sinister as much as presumptuous and annoying.
