For companies like Google, FB, Microsoft, etc which are international companies and have offices all over the worlds is impossible to opt out of this. Google has offices in EU so at the very least their EU business has to comply.

In this essence if your site is running Google Analytics for example, which will collect visitors data regardless of if you do business with EU or not, you have to comply.
If you have FB Like or Share on the site - you have to comply.

These scripts collect visitors data just by browsing your site, or interact with the feature, so disabling EU countries so visitors cannot purchase is not enough. ( post 31 elmirage001 )
