However, your examples are not the best: GDPR and Cookie Law are actually quite good. Regarding the GDPR, I like being able to obtain all the data a business has on me, and to demand that it be deleted. As for the Cookie Law, it’s only a problem for websites using them for tracking people: you are not required to get agreement from the user to use cookies for things like logging in.
Those annoying pop-ups almost everywhere are a disinformation campaign to turn users against that law.
Now, there are other things like the Link Tax you mentioned and the MOSS (VAT on digital services), which means having to charge/pay different VAT rates depending on the user’s country (which you need to justify with 3 different pieces of evidence) that are a big burden on small businesses while not affecting much the big ones to which they were supposedly directed.
MOSS: https://europa.eu/youreurope/business/taxation/vat/vat-digit...
The end effect of those Bizantine regulations is that big companies just use them as loopholes while small businesses get weighted down with them.
Your last line summarizes it well: “The EU is to the German establishment what the USSR was to the Russian establishment.”
