Seems far more likely to me. There's no way that many people are unsubscriing at the same exact moment. It takes what? A few minutes to cancel the subscription. It's not like with concert tickets where someone would be refreshing every couple of seconds to check for the tickets to drop.

Then it's enough that they deliberately took the action to show that it's working.

A job I certainly would like: Chief Emergency Site Fugger Up! Too bad AI is already replacing me there.

I am not sure the self-sabotage approach works. After all, telling people that canceling Disney+ is a thing might nudge a bunch of people on the fence to do the same.

Yeah, it's highly suspicious if just the cancellation page went down. I hope people who couldn't cancel report additional charges as fraud to their banks and credit cards.
