Your stubbornness blinds you and your arguments start losing any rationality to them. Firewire/TB2 were premium data transfer protocols. Created for a niche use — affordable high speed connectivity for pros. And that was exactly what they were used for, quite successfully. They fulfilled a function that USB could not — because USB lacked speed. And they were retired because the status quo has changed.
USB-C is an industry standard interface and connector, designed in collaboration by all the major computer companies and managed by the USB consortium. You know, the group that is responsible for the USB standard. To make it simple, USB-A, USB-B and all other USB connectors are end of life. They are not receiving any updates. They will forever be stuck where they are now. USB-C is the connector that is designed to supersede them. Already that is the reason why USB-C is the future. Its not just an "some gimmicky port by some company who tries to put some nonsense on the users". It is the USB-port. Any future updates to USB standard will rely on USB-C (its designed to be forward-thinking, just as USB-A was back in the day). And it is the port that also supports on-the-fly reconfiguration to support plater of other protocols, such as DisplayPort, HDMI, Thunderbolt3 (which basically includes PCI-express) and potentially anything else.
And contrary to what you say, every major laptop manufacturer is embracing USB-C. As mentioned before, there are hundreds USB-C equipped laptops on the market. The adoption is slow, for obvious reasons, but the companies have agreed on the standard and there is nothing stopping it. As old equipment is breaking down or being replaced, the number of USB-C devices and peripherals will steadily increase. In not too far future, you'll need a dongle to connect your devices to the USB-A port.
Bottomline: I have no gripes with you complaining that USB-C is not comfortable for you right now. There is certainly truth to that. Transition periods are annoying, especially to people who just want to be left alone and do their stuff. But arguing agains basic facts doesn't make any sense.
