I always thought it should be “unlock”, because that’s more what is happening. you’re not buying it, renting has a connotation of a fixed term ownership time, but unlock describes the action… they’ve had the movie the whole time sitting there, probably in a CDN near your home already, but you’re not allowed to see it until you pony up. it’s locked away.
as a gay, I take some undeserved pride in being so terrifying to straight conservatives that many of them started walking around with poop on their butt because they’re scared if they touch their b-hole they’re suddenly gonna “break” and go gay
