Pushed in what way?
I think it needs to be pointed out that following the 180 rule is not the same as boring cinematography. You can absolutely change angle and depth without confusing the spatial positioning of characters within a set. If the shows you watched were boring to watch, that's not the fault of right vs left, that's a different problem.
The 180 rule exists so that it's easy for the audience to identify characters and props within a space. Characters are cast and dressed in a way so they're easy for the audience to tell apart. Presumably, the point of the show--the message the writers/directors/actors etc are trying to convey--has to do with plot, and emotion, and character arcs. If they shot it in a less structured way, presumably those things would remain the same, the viewer would just need to devote a few nanoseconds of brain time to figuring out where people are in the space whenever the camera shifts, because the person who was looking right a second ago is now looking left.
Because you're right, audiences are smart enough to figure it out. But that's the thing--there is still something there that needs figuring. You're giving the brain a little extra work. And that sounds like a good thing, but all recent science has shown that multi-tasking HARMS intelligence. The more things your brain has to focus on, the less it's able to focus on any one thing. It dampens comprehension.
So when someone talks off screen, and my animal brain has a fraction of a second pause of "wait who was standing there a second ago?" that's focus taken away from the part of the show that matters. Does that really benefit the viewer? What argument is there in favor of making it harder for the viewer to follow, unless the point is for the viewer to feel disoriented? (Which is totally valid, too, and people are still making those kinds of stories.)
As for the rest of the stuff I can't comment, because endlessly repeating exposition is something I also hate. But I can't say it's dumbing audiences down, because all of these things have existed since the beginning of storytelling as we know it, and yet people still ARE creating unique, challenging media alongside it. There's plenty of room for all kinds of stories, and the ratio of "fast food media" to "high art" really hasn't changed over time, as much as it seems otherwise.
If more challenge is needed, I'd much prefer if people told complex stories with clear, effective tools, than trying to tell a simple procedural story with artsy ones.
