So that means that no third-party services should be allowed?
When I send an email to a company that uses third-party customer support software to consume, parse, and host the email; I don't agree to the TOS of the customer support vendor.
When I send an email to a company that uses third-party software to parse and archive email for legal purposes; I don't agree to the TOS of that email parsing and archiving company.
It would be ridiculous and impossible to expect that I would agree to the TOS of each and all pieces of software used in the processing of my communications with a company.
