We can argue about how pervasive advertising is and how subtle it can be, but cable TV literally has commercial ad breaks.
For series the episodes are written with commercial breaks in mind. For example a typical "The Simpsons" episode is written as 3 acts and the commercials come between the acts.
Movies aren't written with ads in mind, but usually the cable channel running the movie takes into account what is going on in the movie when they decide where to place their ad breaks.
This makes that ads a lot less intrusive than ads on YouTube or most other ad supported streaming services.
With the ads not actually interrupting the story, they actually often provide a convenient break to get up and get a snack, or clean up after the last snack, or visit the restroom. And I can always pick up my iPad or Kindle or a book to pass the time during the ad break if I don't need to do any of those other things.
For movies pretty much everything I wanted to watch would eventually show up. Typically a movie would first be in theaters, then become available for purchase on disc or digital, rental, and be included in one paid streaming service. Sometime later, maybe two years after it was in theaters, it should show up on some non-premium cable channel.
The only time I couldn't wait for things to show up on non-premium cable was when "Avengers: Endgame" was coming soon. I knew that one would be hard to avoid major spoilers for once it was released in theaters so decided seeing it in theaters was a must. That meant I had to get get a month of Netflix, which had the Marvel movies then, to get caught up enough for "Endgame".
I also liked cable for rewatching TV series. I'm not sure why, but when some channel is showing "The Simpsons" or "South Park" reruns on a regular schedule I like watching much more than I do when I watch an episode on an on-demand streaming service (or on DVD).
I think it has something to do with the latter being more deliberate. I picked that episode, which somehow makes it so I feel like I need to take it more seriously. When it is just "This channel shows a couple episodes every night" then it seems a lot more casual, like listening to music on the radio. It is easier to just sit back and relax and watch.
