While I'm a bit dubious of how they'll define a 'one click' flow, this is a great move. Maybe auto-subscribing free trials can be banned next?
I live in France, and they do everything possible to make subscriptions hard to cancel - I signed up to my gym online, but if I want to cancel it I need to send their headquarters a physical letter in the post, and expect a 4-6 week processing time haha.
