That's because the Swiss DNS blocking originated in an anti-unregulated-gambling law. Basically all unregulated gambling websites are blocked. There shouldn't be any other sites on that list.

I'm a little mad because it's the principle of the thing.

In practice the only site I occasionally want to check that's blocked is Polymarket. I don't trade on there myself, but I find it useful to check the odds of certain events.

I don't personally care about betting sites but it's the legal precedent and principle that the government can add anything to such a list and make obligatory.
