This seems to be contradicted by this article, which say that Facebook will not adopt GDPR protections globally:

Its purely a PR flip flop, people didnt like their message yesterday and advertisers money concerns is a strong invisible hand.

I think they figured out how badly their statement yesterday played.

I'm paranoid about privacy. I would like Facebook to adopt GDPR everywhere. However, I also want Facebook to continue to thrive economically. Benefits of a thriving Facebook are clear, from the open compute project to tons of open source software, and the applications (FB, Instagram, WhatsApp) themselves.

In that light, it's sufficient for me if Facebook follows the law of the land properly. In the US, they needn't adhere to GDPR, but do need to abide by their deal with the FTC. Abiding by that deal would have prevented the CA debacle.

So there - I enjoy free services, software, etc. from Facebook, but just ask that they stay ethical

"Stay ethical"? Since when has FB ever acted ethically?

You are very poor at paranoia if you use facebook. The CA debacle isnt the breach here.
