> 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)
