In Germany, for example, the business has to allow cancelling via the same way as you signed up.

That seems reasonable.

Do you know a lot of companies that will let someone sign up via e-mail? I don't.

I do know of lots of companies that let you sign up via website though.

And IMHO those companies should also let you cancel the same way, whether or not the law requires it. To me, that seems reasonable and fair.
