Earlier quoted context omitted.
That would involve eavesdropping on a private conversation, and as such the analogy falls flat (also since you pay them directly for a service.)
Why can't the phone company listen to private conversations? What does being paid have to do with their enforcement of their own property rights? Couldn't they just say in the EULA "we will listen to your calls and disconnect you if you say something we don't like"?

Because paying for a service establishes certain rights and expectations that patronizing a free/ad-supported website does not. In other words, payment creates a contract.

I suppose in theory, though it would be difficult to show that all parties to the call agreed to such a EULA.
