Bullshit

Apple:

• The web application or social network that we do will be great.
• Our application review rules apply for the common good.
• Nobody needs [a popular new category of products that Apple hasn’t yet made].

Google:

• Android is an open system.
• Do not be evil.
• We request all your private information and monitor all your actions solely for your own benefit.

Facebook:

• Our users want to interact with brands.
• We value your privacy.
• We do not watch you when you logged out.

Each has its own bullshit. You can simply choose which one you want to endure.
