If they offered a customer service option to resolve such issues, probably 90% of requests would be from people who legitimately were VPN users. So they'd have to waste a lot of time to help the 10% of false positives affected. And ironically, the better they make their detection system at avoiding false positives, the more time they'd be wasting on that customer service. So maybe they invest more resources into making the detection system better instead of customer service.
Also, this problem is probably ISP specific. If an ISP routes their global traffic over a globally shared pool of a couple public ipv4's via CGNAT for example, the ISP is virtually aiding the VPN providers which have obtained users from those ISPs. Netflix probably wants the ISP to stop doing that and instead chop up their public ipv4 pool into smaller pools so that they can ban individual sub-pools instead. The market position Netflix is in allows them to keep the users of small ISPs hostage in this situation. They only have to buckle in to large ISPs, if at all.
Anyways, this is a silly waste of time really. People paid for content. People should be allowed to watch it. If they want to watch american shows instead, why not let them.
