Does the FTC actually have the power to set rules like this effectively now that Chevron deference isn't a thing? I'd imagine e.g. the New York Times, among others, will quickly sue to stop this, no?
As a Washington resident, I tested this a while back: nope, you can cancel online AFAICT (I didn’t actually cancel, but the click flow indicated that it should work), and do not need to be a CA resident.
I'm in Texas and was able to cancel online. It was slightly frictional. I had first paused my subscription. Apparently you can't cancel if your subscription is paused, so I had to reinstate the sub to cancel.
