Well yes, I don't like it but what can you do about it, nothing at all, short of fitting false plates or removing them altogether, either way, you're up shit creek.
How about "write to your MP" saying you don't like the police taking the law into their own hands and spying on you, an innocent citizen (which is effectively what they have done)? History pretty much tells us that this isn't a good thing. If you don't like something, don't just throw your hands up and accept it - you have the power to be an agent of change. Or bung a few quid in the direction of the organizations that campaign against this sort of thing - Liberty or one of many others working in this field.
Before writing to your MP, you need MP's and a Government who do not consider themselves above the Law, but's getting too political and will kick off the usual suspects again, so I'm not going further with that.
It's not political, it's a question of civic engagement. If one doesn't like the way the world is, one isn't going to change it by sitting on one's backside saying it can't be changed.
MPs work on the '
BBC letters principle' when they get letters. If the BBC get a letter complaining about a programme they treat every letter received as if it represents \$x\$ people's opinions, the \$(x-1)\$ being too lazy to write and complain. MPs are the same, if they get enough letters and they don't look like an orchestrated campaign* they will react and do something. Even if they are unprincipled lumps of ordure, they want to get elected again next time around so don't want to piss off too many constituents. All it takes is one MP to
start a movement in parliament, and no matter how little you feel your vote achieves, thankfully parliament still makes the law and that law gets obeyed by the vast majority of citizens and institutions.
*If you ever write to your MP/Congresscritter/whatever, always write the letter yourself, don't go lazy and copy a letter some campaign has sent you. A copy of a campaign's form letter gets counted as 'one voter', your personalised letter gets counted as 10, or 20, or 100 voters.
