MIT license lets you do what you want with the code. That's the deal. The blob storage thing is the real problem though. Nobody talks about it until they try to move their models somewhere else.

Well, yeah, which is why it's silly when people use MIT licenses and then complain that those, for example, with the motto "Build > ask. Disrupt or die.", only take and don't contribute anything back, instead of using a license that demands it.
