ISP can't actually deliver said data, and so, can't deliver on their promise.

I can't see how this is Netflix's fault. ISP makes a promise, ISP can't deliver.

Yes it does happen to be coming from Netflix, but Netflix didn't FORCE the ISP's customers to become Netflix customers, did they? Or does Netflix not only have some magical ability to FORCE data upon people, but also mind control to MAKE certain people sign up?

You're arguing that the ISP should be allowed to overstate their capacity as much as they want, and if it causes any problems anywhere, that the counterparty is at fault no matter what. That's completely nonsensical.

Basically they're complaining that they have to make good on the promises that they've made to customers. They were hoping that they could way, way, way oversell their capacity (and charge more for a theoretical peak capacity that you can never use) and get more money from their customers as a result.

Now what's happening is that many of their customers are asking them to make good on 10% of their promises all at the same time. This causes problems for the ISP, so they flail about trying to blame other entities than themselves.

Nobody is asking the ISP to give them a HIGHER data rate than they've already paid for.

They're asking the ISP to give them a mere 10% of what they've already paid for.
