> telling people to contact their ISPs about this, when it's so obvious that the problem is on Netflix's end

They are telling them to contact their ISP because either their ISP directly or the ISPs customers(or the person complaining) are using the ISPs IP addresses to circumvent geo restrictions.

So, I'd wager it's more likely the person/the persons household themselves have either wittingly or unwittingly been using something(e.g. Hola VPN) which enables others to proxy through their home IP (& vice versa)

Imagine a car wash not allowing me to wash my blue car because someone robbed a bank in one of the same color.

Then imagine the car wash told me I should talk to Chevy because it's their problem.

Imagine someone is using your actual car / ip to rob banks. And then you drive through the bank line and they don't serve you.

What a bad analogy.

I'm collateral damage of this change, and this definitely isn't the case for me.

maybe ISPs are misreporting IP blocks as residential addresses while selling them on the side to some VPN providers?
