It's not inevitable. That's not what that word means.
Intel Macs supported Linux because they used Intel's Linux drivers and supported bog-standard UEFI. There are no preexisting drivers or DeviceTree files published by Apple for Linux. There is no UEFI implimentation, just a proprietary bootloader that can be updated post-hoc to deny booting into third-party OSes.

I would love for Linux to support as many ARM devices as possible. Unfortunately, it requires continuous effort from the OEM to be viable. I've bought Qualcomm, Rockchip and Broadcom boards before, none of them have been supported for half as long as my x86 machines are. Nevermind how fast ARM architectures become obsolete.
It feels like Apple is really the only hostile party here, and they coincidentally decide whether or not you get to use third-party OSes.
