>At the moment, anyone can use Linux; it's better and easier than ever. Will the laws of your country make it harder or more difficult to avoid? Will major vendors lock you out of basic functions?

Somewhat related, but if x86 loses dominance it will be even more difficult if not impossible to install Linux or other alternate OS's on ARM devices. The majority of consumer ARM electronics make it hard enough, and normally requires you to run a specific patched (and most likely outdated) Linux kernel in order to boot.

There are ARM devices which meet the ARM System Ready standard which allows you to boot whatever OS you want, but they are mostly enterprise devices such as servers. Cheapest one I've seen which your average consumer might buy was an ARM workstation with a starting price of about $1500
