Admittedly, higher effort and probably not for the non-tech but...android emulator + mobile app would probably work too. Granted I have other qualms with their mobile app.

Tell that to Aaron Swartz.

Aaron Swartz was charged with fraud and unathorized. Not breaking TOS. The idea that breaking TOS could constitute a crime has been shot down by the Ninth Circuit Court of Appeals. http://thefire.org/article/14389.html

Funny, but I was serious about getting my subscription cancelled without refund.

Is that a joke or serious statement? Can't tell thanks to Poe's law.

Kind of a joke, kind of serious. It's what's at issue in Aaron Schwartz' case. The prosecutions argument is that his actions were felonious on the grounds that his violation of the ToS implied Unauthorized Access, which is a felony.
