If you’re not watching netflix whilst working from home, and you’re not going out on your bike, what are you going to be watching………………….
It’s not the ISPs that are reducing the quality.
But it is their infrastructure forcing the issue.
Presumably there must be some clever stuff they can do to reduce their overall bandwidth before they actually drop the bitrate of the files. I’m thinking things like reducing the buffering to eliminate things like people starting to watch a 2 hour film, it buffering the whole thing and them stopping after 5 minutes (not an engineer at Netflix, just hypothesizing that a 25% reduction in bandwidth might not actually precipitate a 25% drop in bitrate).
