Nope, completely missing the point.
The UK and EU are - post Brexit - now competitors, there's a huge amount of bitterness between them, and both sides can (and should) expect the other to stick the knife in should the need, or just opportunity, arise.
But Ireland is not a competitor to the EU, it's a part of the EU, and a part that the EU has repeatedly said is at the heart of the EU, with the non-border border at the front and centre of its decision making process.
It's not the UK that the EU attempted to shaft last night, it's fucking Ireland.
