I support this only because I've been wanting to make a number of large tutorials and example files but don't feel like it's worth it. It's taken a long time and a lot of work to learn some of this stuff, so just posting it for others to take and use at no cost doesn't seem fair. That and, well, it seems like a decent way to bring in a few bucks (Scirra too if Spades' idea is considered.)
Then again, yes, some people will probably take all of these 'templates', slap them together, and start an onslaught of crappy copy/paste games. That seems like the only (yet major) drawback to me.
I dunno..it worked for Stencyl..I think..
