I like how Apple's "Gatekeeper" name says exactly what it is. It's cool how we sleep walk into a computing world where you are only allowed to trust somebody as long as Apple, Microsoft, Google, etc. also trust them.

(Note I had dalliance with Apple products a long time ago. I don't currently use Android. And I only use Windows at work because its a requirement there. But dealing with one or more of these corps are largely unavoidable to most of us.)
