It’s much better to set a Referrer-Policy header, as the browser will honor this.
But yeah, if it’s done through JavaScript and info is added to the URL, then there isn’t much you can do apart from using something like Neat URL.
Danish pede here. There is absolutely no evidence of this. I follow several politicians, who are involved in the efforts with the epidemic law, closely, and I haven't heard a peep about it being scrapped.
With regards to the use of coercion and force, this has been part of the epidemic law since (at least) 1980, so it isn't new, but as I understand it the new law makes it much easier for the government to use the law in situations that are, today, not classified as an epidemic. THAT is scary to me.
I will say, though, that this is the first I hear of the banging of pans etc., it definitely isn't getting much media coverage, which is strange, because the law itself--and the feedback on it from various organizations who are very negative--has been covered.
And Russia. All the animal lovers regard this as a victory. But in practice, we treat(ed) mink very well in Denmark--it is (was) the way to get the best fur.
I would not recommend Ghostery, they have been selling user data. uBlock Origin is MUCH better.
