Of course you can use the modules on any other brand of laptop. It's not going to look pretty doing it, but I've routinely used the USB-C to USB-A, as well as the mini SSD, on a MacBook Pro.

Colleagues borrow them all the time when they need a SD card or MicroSD card reader. Is it as pretty as a dedicated reader for those cards? No, but it does the job.

Saying they're proprietary is misleading a bit. The form factor makes it awkward to use elsewhere but they work just fine anywhere you plug them into.

Someone's making a usb hub that you can plug expansion cards into, but it's just a kickstarter last time i checked and not a very good price

It is not mechanically fit for purpose.

You can likewise put 26" rims on a Ford Fiesta but it will look and function equally poorly.

Slap on a 4 inch extension cable and it's not meaningfully worse than any other dongle.
