Those numbers don't make sense to me. I just watched this video[1] in 4K 60fps on Youtube. I think it's ~5GB. I watched it at double speed so it took 15 minutes to watch. Your second link says it takes 5.12 kWh to transfer 1GB, so it took 25 kWH to watch that video. That's about $5 at California power prices. Did it really cost $5 to watch that free Youtube video?
My ISP caps me at 1.2TB/month. That would be $1200/month, but I don't pay anywhere near that.
25kWh in 15 minutes is 100kW. That's 150x the max amount of power my overpowered desktop uses.
On HN people claim AWS overcharges on egress pricing. They charge between $0.05/GB and $0.09/GB[2]. Their "overcharging" price is much lower (5% - 11%) than the cost of electricity if your numbers are correct, which doesn't make sense. Their ingress price is free, so they're not making up for lost money there.
