This really is not a service issue. This is not a privacy issue.
YouTube as a service is ... actually a great service, it pays creators well, it's fast, it has decades of content, and it has tons of features.
It's monetized with ads, you either watch those ads or you pay them. Using a VPN to get a lower price on the subscription is not a service issue, that's abuse of regional pricing, and no company would accept that.
