Pretty much the same as using Cable TV or Satellite TV without paying for a subscription. I don't see much difference between paying the BBC and paying Comcast.
In the case of Satellite TV, in the 1990s there were companies that sold decoder boxes so you could use a dish antenna without paying the Satellite TV company. You'd pay the pirating company instead. Lots of cat-and-mouse games involving changing encryption methods.
