Not all. While commercialization of the creator culture undoubtedly has some benefits, it also kills some of its original "soul".

Someone making funny videos on the internet on their free time without any kind of expectation to make money out of it unavoidably produces different results than the same person making semi-professional videos on Youtube and making living out of it. If the latter is an option, why the hell would the said person do the former? But since the latter option exists, it drives all of the creations to more professional, less quirky direction. It's the same effect that causes all the Hollywood films to have pretty much the same story arc and all the big budget games to feel like copies of each other.
