It’s also possible to… “move” to California for long enough that a “Cancel” button magically appears in your account setting a page. This was true for WSJ who otherwise wanted a phone call with hold times.
It's the problem of a two-party system. Apparently wanting easy online cancellation means you need to support an entire debt-ridden, tax-heavy, welfare state that encourages high crime rates, violent criminal releases, and penalizes self-defense.
Well, there's a mechanism for that. I believe other states' residents don't care as much about these things, though. For instance, the amount of work required to make this law in North Dakota is pretty low, but I don't think it's going to happen.
