Did anyone actually read the article? Most of the comments here are treating the article as if the UK will depart from GDPR (as the title says) - but the article says nothing of the kind. It will be a slight change, probably reformatted to allow for less red tape and more clarity for small businesses and early-life enterprise. And the UK still needs to keep regulatory alignment to the EU to be able to have low-tarrif access to the markets.
If I was a betting man, I wouldn't bet on this being a significant change, given the world is moving more towards privacy (yes, including US).
