The EU was actually on the path to forcing everyone to use micro-USB. Thankfully Apple (and others) pioneered USB-C (bringing what it learnt from developing the lightning connector) in the time it took the EU to go from making all of the phone makers sign a Memorandum of Understanding to making it legislation. Now the EU is frozen in time, stuck on USB-C for the forseeable future. The economics to make a device dual port (USB-C and something new) aren't there, so we're not likely to ever see an improvement on USB-C... in an alternative timeline, we could have been stuck on the even worse micro-USB.

Bringing it back to the topic on hand, this is very much an area I wouldn't want to see a heavy handed EU legislate something that just further cements the incumbants and makes everything worse forever... just like mandatory micro-USB would have been. I can totally see the EU legislating something like a mandatory Meta communication protocol with compulsory attestation from Meta servers.
