Bullshit

Apple:

• The web application or social network we make will be great.
• Our application review policies are for the common good.
• Nobody needs [a popular new category of products that Apple doesn't yet make].

Google:

• Android is an open system.
• Do not be evil.
• We ask for all your private information and track all your actions solely for your good.

Facebook:

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

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