But unless you actually cancel your subscription, that's not a bad thing for Netflix. All the time you're not in there watching content is time you're not consuming bandwidth or CPU cycles, etc. It's kinda like a gym: the perfect customer is somebody who signs up for a membership, and never shows up again, while keeping their membership active.
Now I know some people do the whole "binge for a while, cancel my subscription and come back in a couple of months thing." A good friend of mine actually does that. But I suspect most people are too lazy to bother, and keep their account active even when they aren't actively watching something. But maybe that's just me projecting? Hmmm...
I also do not subscribe to HBO Max in part because of that
