EasyDNS has an interesting position on GDPR compliance for businesses not based in the EU:
"All prior history of internet governance would have us taking the position that being a Canadian company we are going to operate by Canadian law, and not by European law."
Also:
"Sure, Google and Facebook and Apple do have to worry about this, because they’ve domiciled their foreign HQ’s in Ireland so that they can shelter all that foreign revenue from US taxation."

@starbreaker They have to obey by EU standards in cases where they are serving EU customers really.
Still... implementing GDPR is just good manners at this point.
@mareklach I agree with the second point.
As to the first: if I ran Google I would have started closing all offices outside the US the second I knew about GDPR, repatriating all revenues into the US and paying US taxes, stop censoring search results in China, and count on Uncle Sam to shield Google from foreign law enforcement. 🖕
Of course, if I ran Google I wouldn't have allowed the business to become so heavily dependent on adtech in the first fucking place. 
@starbreaker Well, Google can still operate android and play store in EU, where the purchase is a consentual buyer's decision.
But you're right, they should have to scale down their add business in the EU, because only few people will agree with having ads served to them.
Perhaps they could serve very generic ads without tracking users, I am not sure...
@mareklach There's no reason they couldn't.
For hell's sake, I could do that myself. Want to advertise on my website? Gimme a hundred bucks and I'll run your link and up to 500 characters of copy at the top of every page on my site, right under the nav menu.
I could rig that shit up in less than an hour, and it wouldn't require ANY javascript.
If I can manage it, there's no excuse for Google to be unable to provide dumb ads.
