It isn't just the UK. The USA started with the ESTA thing, previously I'd just fill in the "visa-waiver" form on the flight. Then (I guess in response) the EU (while the UK was still a member) agreed to the ETIAS scheme. Is has simply been delayed in its introduction - it was supposed to be operating now. Hence affecting US and UK citizens traveling to the EU, and for the latter "regional travelers". So why should EU (or US) citizens traveling to the UK be exempt from a similar experience? It isn't related to Brexit, As such. It just seems to be the way the world in general has been heading over the last 15 or so years. (Brexit obviously has an impact both ways for EU/UK citizens, as within the EU club FoM applied. It doesn't any more - either way. So no-one is being singled out)
