I know so little about data security that for years I thought that GDPR was another way of saying East Germany. My ignorance is little better these days but I do know one thing. If the UK tears up its data security rules which it agreed while a member of the EU, the EU will tear up its data sharing agreements with the UK.
All firms using data in the EU or even with any firms in the EU, or who want to do business in the EU, will still have to follow GDPR or lose contracts. So, this is yet another example of cutting off your nose to spite your face.
There are no gains that can possibly outweigh the costs of big changes in data laws. So the UK is very likely to stay as close as possible to EU standards. The changes are pointless if that is the case and extremely damaging if they are not.
In either case they will also cost British companies money just to comply with two sets of rules. Pointless flag waving costs.
Economics, trade and Brexit, not necessarily in that order but the dog always comes first.
I may be woefully misintepreting this, but if the UK removes itself from the existing data protections, does that leave every phone user in the country susceptible to round-the-clock nuisance calls from cold sales teams?
