This "warning" by Rixstep is pure FUD.  Rixstep are kind of like the trolls of the Apple development community.  They regularly publish "industry watch warnings" about changes in the Mac development ecosystem that are factually incorrect at best, and are intentionally misleading to imply that Apple is killing off Mac development. I don't think anyone takes these guys seriously. Many Mac developers get upset at Rixsteps's constant barrage of fear-mongering, lies and factually incorrect "technical articles" (that are designed to make it look like the Mac SDKs are incapable of doing basic things, which they can actually do quite well).
