I've seen people count clicks and complain that is not as easy as signup.

To signup they just went to foo.com and there was list of plans with links to their sign up pages right there, so click one of those, fill out the one page form, click submit.

To cancel, they have to go to foo.com, click the login link, full in the login form, click to submit, then on their home page click on the profile icon to get the profile menu, click account in that menu, and then click the cancel button on the account page.

That's 2 clicks to sign up and 5 to cancel--6 if the cancel button asks if you are sure.
