This might be a non-issue. The only people who are likely to care about installing alternative operating systems are power users, and power users may still prefer to buy more powerful Intel systems.
As a power user, I'm still looking for a good ARM battery efficient 2-in-1 to use as a light laptop and tablet that runs Linux. Not to use as a production machine but for content consumption. Being able to continually read a book or article while coding or performing a task on production machine would be better then having to swap between the two on one computer. Wouldn't choose Intel for that.
Having more shipping ARM devices gets you closer to that, even if these devices have a locked bootloader. The more robust the ecosystem around ARM with UEFI gets, the more the parts become commodity and if there's enough demand, someone will start shipping them with Linux or unlocked bootloaders.
(Hate UEFI all you want, but standardizing on something is much better than the Android world where every SoC requires a custom bootloader and if the manufacturer doesn't support the kernel you want to run, tough. Having a standardized platform to run on means you can have a Linux distribution that supports running on any device that supports the standard.)

Traditionally, one of the ways people got into Linux was inheriting an old box and sticking Linux on it. You won't be able to do this anymore.
And as Intel will become more and more niche, it will get more expensive.
