Me and my wife do as well. Just because I only have 50 subscribers doesn't mean that my hours of editing are any less important or likewise my opinion on the matter.
That said, I use the term "work" loosely even in reference to myself... Video editing is fun. Playing games is fun. Sharing my gameplay online and people posting comments is fun. The moment ANY of that became work, I'd be out of it.
I'm not saying people aren't putting effort into what they do in LPs, my point was simply that instead of bitching and complaining because a company doesn't want you making money off of their IP, you just go to a more charitable developer if it bothers you that much. As I've said before, I've had MUCH more problems with Capcom than Nintendo in content matching... and as a result... well... not much because again I don't care about my measely ad revenue
But if it DID I'd just stop playing Capcom games.
