Apple has been slowly tightening the screws on app notarization (code signing) requirements for running apps on macOS. To do it properly you need to be a registered developer ($100/year), and they're certainly not making it easy if you don't have access to a Mac.

I suspect the friction that users are facing are due to dodging the above requirements.
The whole sdk has a restriction that you can't use it off platform. The code signing thing is just a tax on ios devs
You need an apple ID. You cannot create one without using an apple device.
You can absolutely make an appleID without an Apple device. You can make one in-browser right now. https://account.apple.com/account?create
