I mean that - whatever the legal details - Facebook clearly feels that it is now more useful to manage British data under a jurisdiction that was not an option before, an option that was held up as offering significantly less protection than under the EU. I don't buy the equivalence in toothlessness either - the EU seems to have a willingness to take on big tech overreach in a way UK Gov has neither the capability or willpower going by past performance.
