The creator is sending the content to my machine for free. Whether my machine displays the ads (aka cancer) attached to that content is my decision.
Also regarding paying money, don't forget in pretty much any case you still end up tracked. If anything, you get tracked less by the ad-supported version because at least you're not giving them any billing information and are not consistently logging into the same account (which you'd have to do for your subscriber benefits to kick in).

I'd love such a choice as it will allow me to say no to cancer & stalking once and for all. However it will have to be implemented in such a way that it's technically impossible for anyone to track me through the subscription system.
