I think he is referring to websites that are now blocking all EU users because of GDPR.
I'm surprised companies aren't just pulling the same move porn/alcohol websites use with age by asking the user if they are an EU citizen/in the EU and if they answer yes, send them to a static "we don't service the EU" page at which point everyone just lies so they can still access the page with the tracking.
GDPR is fine with the selling of information, as long as you have given consent in clear language and not buried in TOS.
