It's not "We're a private company" as much as "Google cannot practically force you".

Google also doesn't have anywhere near a monopoly position in consumer markets.

You could even build a private one, or rent space from Vimeo or Dailymotion.

The Founding Fathers can go &&*k themselves. Invoking their name is literally appeal to authority.
