Marco has a point. When you read his blogpost, this is how you should actually read it:

Apple:

• We'd like you to use our web app or social network instead and will annoy you until you do.
• Our app-review rules are always in someone's best interest.
• Anyone who wants a [popular new product category that Apple doesn’t make yet] should just curl up and die.

Google:

• Android is using other people's work.
• Don't look evil.
• We solicit all of your personal information and track everything you do because that's how we make money.

Facebook:

• Our brands want to push their products onto our users.
• We value your privacy as much as we think you do.
• We're not tracking you when you log out. We simply never log you out.
