Most stuff people use USB for still have the good old USB-A adapters: mice, keyboards, USB sticks/other drives, card readers, LTE dongles.
The things that actually need the massive speed benefits from USB-C (10G network adapters and PCIe enclosures) can have USB-C, fine with me, but please don't force users to buy and especially lose adapters just to be able to use their existing stuff. And no need to make shit ever more expensive and complex, a mouse won't ever need anything from USB-C.
I have a hard time understanding people that just keep complaining about the new USB-C ports instead of just buying a handful of those (https://www.amazon.com/dp/B07CVX3516) and permanently attaching them to the mouse/keyboard cables.
