It is fairly simple to print off a form and send it in to your GP but I suspect the vast majority of people will see this as a hassle and never bother.

Considering recent government actions, I find it unsurprising that this is the only method - as far as I can find - to opt-out.

A simple form or email address would have been great. But we couldn't possibly have that for an online data service, oh no.
