Many interfaces of yore didn't do USB (especially ones with lotsa I/O). So many jumped on the FW train due to bandwidth and the fact that USB 3.0 just wasn't in audio hardware developer's sights.

Apogee Ensemble Firewire. A Thunderbolt replacement would be $2500. There are other, less expensive options, but I'm still stuck with a minimum of $300 (new interface that supports ADAT, reuse the Ensemble with that) and probably upwards of $1000 to get equivalent functionality. This, on top of the cost of a new computer.

Yeah it may suck for you, but it won't suck for the people that buy whatever this equipment is and then use it over USB-C once that company makes the conversion.

It's like if we had no common way of measuring things. Imagine having to walk around with like 10 different tape measures because there was no standard. It's stupid. All of these different port interfaces are just like that.

Yeah. It's no big deal. Santa will be coming by real soon with new shiny USB Type C toys to replace our obsolete ones. It's a good thing Santa can write blank checks.
