That's a bit of an exaggeration. Those that try to collect as much data as possible data from visitors will of course find it difficult to be compliant, but many do not do this and are therefore in compliance with GDPR.

I do find the propaganda against GDPR annoying though. As an EU citizen (and someone who had to make sure we were compliant on multiple projects) I am happy about it. Is it perfect? No. But it's still waaaay better than nothing.
