So, this sucks, but basically puts them in line with other streaming services. They aren’t showing, like, commercials from other companies. They’re showing promotional stuff, like trailers for their other movies or shows. Usually they can be skipped, although Disney apparently does say sometimes you won’t be able to.
As far as I know most streaming services do these preroll promotions at least sometimes. It’s never really bothered me, because I skip them.
This is still different from the product and service commercials you’ll see on ad-supported plans.
Please note that I am not defending the practice, just clarifying.
Edit: Again, in no way am I trying to say this is a good thing. It’s a bad thing. But as bad things go like, on a spectrum of bad, it’s not as bad as seeing commercials for Taco Bell or something. (I understand nuance is hard, but it’s important, broadly speaking, for my sanity. Not that my sanity is in any way tied to Disney’s streaming services, just that I’ve gotten a lot of practice in nuance.)
