Does he actually say anything in these videos that unambiguously violates the youtube guidelines?
There are plenty of very clear cut examples of Google banning people for spurious reasons; I'd rather get up in arms about those.
Edit: I think I misunderstood, you're just pointing out that he didn't say anything at all, competitive or otherwise. It got my attention because I have some silent videos that are used to supplement some application notes and would rather they didn't get my account banned.
