After over 3 decades as a gamer and tech user this is maybe the single most consistent important benefit for any open platform were you can just install Linux.

The rest is nice but this one means that 10 or 20 years from now your hardware might have been repurposed for something else and still be useful and in use whilst a closed platform will just be more junk in a junkyard or sitting in a box of those things you’ve kept just because you don’t like to throw expensive stuff away but will in practice never use again.
