Does it?

user A uses their full bandwidth from 2am-4am when the network is empty then watches a 720p video at 5pm (or whenever the networks peak is).

User B watches an 8k video at 5pm and nothing at any other time.

UserB clearly contributes to congestion on the network more than user A despite user A using more data. Furthermore throttling user A does less to resolve the congestion than throttling user B.

IMO If the network needs to throttle then the people the most data at that instant in time need to be throttled and the network needs to start upgrading its infrastructure or amending its marketing materials.
