I see that ISPs (companies) generally want to make more money. Attempting to charge Netflix is an attempt at that. If they are not able to charge Netflix this extra amount, wouldn't it be logical for them to charge consumers more?
As it appears in Netflix's statement, their network is congested. If ISPs want to keep their profit ratio and offer better services to their consumers. Somebody has to pay more. I doubt they would settle for anything less.
Again this is just me. I would be interested to hear if there would be anything preventing ISPs from charging their customers more...
