Creating a one-connector standard that can be used to plug a metric ton of different I/O standards was never meant to be simple or easy.
All that information doesnt negate anything that tweet says, or the advantages of the universal connector. Stuff mostly will still just work because there are a lot of failsafes in place, and the whole thing will fall back to the minimum it can support under the conditions, even if it is for example USB 2.0. Sure, people will need to be educated on optimisation because they are used to the simplicity of if it fits here, its the adequate cable but in this day and age thats less and less of a worry, many people plug into their laptops barely anything else than the charger, a USB stick and eventually a mouse sometimes, and there will still be a big advantage in the connector being the same for everything instead of each of there being different connectors with specific use-cases.
This is not something that will magically get fixed going forward short of all the very possible protocols (HDMI, USB, Thunderbolt, DIsplayPort, power standards, etc) get merged into one which is unrealistic and unfeasible, so unless youre suggesting that Microsoft et all backpedal on the USB-C plan, I dont see whats wrong with the tweet at all. There may be an issue with the message that the manufacturers need to pass to the public, but not with the port.
