You're trying to make this out to be a principled stance about "spreading ideas", and yet with every post you undermine that claim and make it clear that it's really about "Dustin Curtis is a jerk, so fuck him."
Ultimately, what's valuable about Svtble is where Dustin's capable of taking it, both as a network and as a platform. These spinoffs can't touch that, because they're not Dustin. If Dustin ends up launching a great platform, then the copycats won't be able to touch him. Until he launches anything, however, I see no problem with people seeing his concepts and launching copycats, especially not if they're open-sourcing the clones.
