The majority of homebrewers, or rather homebrewers without modchips as well, don't pirate anything. That is a pretty qualifying statement, but most people avoid that stuff, myself included. Most people who installed pirated WiiWare/VC channels have stopped too, or at least a big chunk have, since Nintendo has started taking action. I'd have to say Nintendo is doing a pretty good job at protecting their assets, and I don't think they care about people running custom code on their systems, but there's no way to have it one way or the other. The latest update does stop modchip-only users from installing hacked VC and WiiWare, but also blocks imports, because Datel sucks. You can run imports if you install a program called Gecko Region Free however.
