The problem of something like Google Analytics is that a company in the EU (EU company, US subsidiary, ...) exports PII to the US which it can't do (law interpretation is not clear inside the EU, e.g. is it legal if GA doesn't store IPs or if using GA without consent is generally illegal).

And exporting data to the US is illegal because US companies can't guarantee that the EU citizen data is protected (which is the goal of the GDPR).

But then again, it is not clear if this applies if an EU citizen goes to a company in the US (real or website in US datacenter) and leaves their data there.
