The evidence that you're wrong starts by the fact you already started from the "We" are the winners and "They" are the losers, so "They" are playing dirty and "We" are the real victims here.

If you haven't read the investigation documents and ruling ( as I didn't ), the most we can do is having a hunch and googling Amazon's past and track record in everything from business tactics to employee policies, I think no one is surprised they have problems with the law.

And speaking of law, each place has their own laws, customs and views on how society should look.

Usually the burden of proof is with those making the accusations

The EU's focus on data protection, particularly the German view, which is to a large extent that which now prevails at the EU level (though the others were very similar), predates the existence of these tech companies. By a huge amount.

In Germany, it is considered a "Grundrecht", a "basic right" of constitutional rank.

It's actually pretty easy to see the pattern, isn't it? The US tech giants' business models most often are based on data usage that is inherently incompatible with GDPR (Most are esssentially advertisers). And apparently most of these companies continued that practice despite the GDPR.

Most EU tech giants are B2B and mostly don't have this problem in the first place.

Why do you think EU tech companies are nonexistent?
