I don't support this, but I can try to steel man this position.
Largely it comes with the idea that use = cost, and that infrastructure has limited capacity and is therefore zeroish sum. For example, a common idea is that we should tax trucks more than other cars because they cause a large amount of damage to our roads. Following that logic, the companies that encourage users to consume more bandwidth should be charged a price for that since they're the ones making money on it, and we don't want to raise costs on users.
