The UK Met Police raided Facebook’s offices after the Brexit vote, to seize all the data on their servers and uncover their collusion with Cambridge Analytica.

After Brexit was enacted, and EU protection was lost while the UK government turned a blind eye, both Facebook and Google started hosting all their UK data in the US, outside the reach of UK law enforcement. This occurred literally on the day Brexit came into force.

Another thing that happened on the same day was MasterCard and VISA raising their transaction fees, from the EU limit of 0.3%, to 1.5% - they increased their fees to 500% of what they were the day before. And then inflation happened.
