This seems to be in agreement with what I said, but you appear to have put it up as a counterexample. Showman means entertainment. He's an entertainer. He also seems to be one of the rare entertainers who doesn't fib for greater entertainment value. The LTT labs thing linked elsewhere suggests he cares about the technical side and, like BuzzFeed News, wants to use entertainment to fund more serious stuff.

I don't see a problem here. The keyboard thing sounds entertaining, so I'll go check it out.
