Nah, they’ve always been like this. The two-season limit has been A Thing since early on.
Which is dumb as hell considering their early success with The Office. They know people want a big-ass series they can watch over and over. Doing that in-house should be a dead easy way to prevent competition (until we claw back mandatory syndication from these bastard petit monopolies) and avoid licensing their cash cow from another company.
What really pisses me off are the showrunners who do cliffhanger endings anyway. You know you’re not getting a third season! You aren’t doing Stranger Things numbers. Don’t blame the lawnmower when you stick your hand in, you know it’s gonna cut you short and feel nothing.
