It's probably a formal agreement with Netflix, but I'm speculating.
Short term, ISPs can't increase bandwidth availability, and Netflix can reduce bandwidth consumption.
And I'm not sure it's a nonissue. The videos in my online classes are pausing every few seconds lately. And watching those in a lower quality isn't an option because the writing needs to be readable.
On the other hand, Zoom works better than EdX, so it may be the EdX servers that are overwhelmed.

>ISPs are prohibited from blocking or slowing down of Internet traffic, except where necessary. The exceptions are limited to: traffic management to comply with a legal order, to ensure network integrity and security, and to manage congestion, provided that equivalent categories of traffic are treated equally.
I wonder if anyone here knows if the EdX servers are overwhelmed.
