I have no idea why it seems to be so hard for VPN providers to get IPv6 right. The technology has been here for ages. Also, unlike physical ISPs, VPN providers have no other way to differentiate from each other but getting this sort of things right, so one could except them to be motivated, but no.

They separate each other by spending money on YouTube ads and sponsorships and jacking up prices to offer 50%, no 70% no NINETY PERCENT DISCOUNT if you subscribe for 17 years using my promo code MisterSandman!
