The thing about standards is that there are so many of them to choose from
North America isn't like the rest of the world.
Due to misplaced overconfidence from the legacy manufacturers who convinced themselves that EVs in America would only a be fad and a lack of investment, Tesla superchargers represent over 60% of the available rapid chargers over there. If you want to go on longer journeys off of some of the better trodden routes you had better be in a Tesla or you might not get there, so this move shouldn't be too surprising.
As someone else above pointed out the CCS connector used in North America isnt even the same as the one used in Europe and the test of the world, CHAdeMO is pretty much a dead duck now outside of Japan and China has its own standard too.
I think Tesla represents 15-20% of the available charging sites around UK and Europe, so its CCS rather Tesla is the one with market traction (not to mention compulsory EU legislation on its side) I dont see anything other than CCS becoming dominant here.
Its not that hard to fit two cables to chargers, much in the same way fuel pumps often offer, unleaded, premium unleaded and diesel. In the UK upto now they tend to be CCS type 2 and CHAdeMO but I can see that quickly changing to become CCS type 2 and Tesla
