Theft? Of what? I'm pretty sure making a fork is not theft. If it is, the crypto community is a community of thieves.
So what they took? The "roadmap"? That is weak.
Sure they are doing what Crypti wanted to do next, but can you blame them they don't want to do it there after seeing the ineffectivity of the fondation method?

If (as they stated) the Fondation have accomplised most what they set out to do, the technology is working, the only problem is lack of interest, no community and dapp development. Well, that is Maxs' department. The developers, already got paid for their work from the ICO funds, I won't cry for them if Max not working on making them more money by raising XCRs value.
I would feel differently if they'd continue to work on making crypti more succesful, but that is clearly not the case, at least it wasn't in the last few months.
