I mean sure, he might not single handedly save tf2 or whatever and might not be the most skilled editor out there but content creation in general is such an important point in a community. Sure, we might roll our eyes at those guys with their rather silly pub clips but we might not be the primary target group after all. But this guy and his lads we're pumping out content like noone else which was greatly received, reaching thousands and thousands of casual players, keeping them interested in this game, maybe even long enough until some of those casual players try out comp at some point. We all started somewhere like that. I really don't think that's "overrated".
