Apple:

  • This web app or social network we’re making is going to be great.
  • Our app-review rules are always in everyone’s best interests.
  • Nobody wants a [popular new product category that Apple doesn’t make yet].

Google:

  • Android is open.
  • Don’t be evil.
  • We solicit all of your personal information and track everything you do to make things better for you.

Facebook:

Everyone has their bullshit. You can simply decide whose you’re willing to tolerate.
