I don't care about MAX SPECS ALWAYS, I don't even really care about the port used, but I can see the benefits of a common port on all small rechargeable devices, if the EU wants to regulate this I fail to see any argument in your long post about how Apple is somehow going to be prevented from trying to invent the next port. What Apple may be prevented from doing is having a unique port just for themselves, no one has yet given a concrete example of Apple using their proprietary port for anything special that a generic port everyone could use can't accomplish.
Lightning was great when the only other options were the 30-pin connector and micro-B, and it could have been a great replacement to USB if Apple had pushed for lightning to be the standard for USB-C. They didn't, not because they couldn't have but because they wanted to keep that nice lightning lock in and MFi Licensing program going.
Apple is free to contribute to the next great port design and push for its adoption so this law has only imaginary effect on preventing future innovation. There is nothing here preventing a new standard being rolled out in the future.
People keep bouncing around on innovation without providing nay concrete examples beyond the shape of the port which Apple could've pushed to make the standard (as I keep repeating).
Apple isn't hurt by this, innovation isn't hurt by this, a standard port hurts no one and helps everyone. If the port chosen is less than ideal that is partially Apple's fault for fighting this process every step of the way rather than contributing productively.
