That's leads to a pretty simple conclusion, because Netflix doesn't push any data. I pull data from Netflix. I have already paid my ISP to pull data from anywhere I ask. If my ISP sits down at a negotiating table with Netflix and threatens to disrupt that, they should be laughed out of the room. "Pay me, or else I'm going to break my obligations to an unrelated third party." isn't a move that should have any respect.
But the problem is the people that could get affected by their actions until they stop.
Regardless, Netflix is not pushing content. The consumer is pulling it.
As a one-off, issues like the Squid-Game aren't so bad, but if it's a chronic problem for the ISP then it's because their model of consumer consumption was wrong.
However, that would leave free content inaccessible, and probably create another wealth divide.
Imagine if the same principles were used in other areas. You iPhone suddenly locking up after using Facebook to much because Facebook wasn’t paying Apple for access to its users.
