This confirms my impression: the conversation does not have to go sideways about advertisements. It is kind of a deflecting trick to provide customer support instead of cancelling the subscription. Once you step in their trap, then it is slightly more cumbersome to go through the cancellation process.
I guess people try to be polite and come up with a reason for cancelling their subscription, and this reason could be solved by customer support. It is not being polite to try to please Tony from customer support, he is just doing his job and does not care about polite reasons for cancelling, his job is that you do not cancel. It is important to know what you *really* want before contacting them (or any other company), in case they use this kind of trick to confuse you.
