Most websites are voluntarily blocking VPNs. Reddit, cesspool that it often is, is one of them. I recently bumped into some sites that help sail the high seas blocking VPNs, which was rich.

So while I agree with your broader sentiment, I think many sites will just find themselves blocking VPNs for reasons other than laws or age verification bypass attempts.

That it looks like they’re complying with idiotic legislature is simply a side effect of pursuing other goals/ends.
