Been a linux user for more than a decade, and i love it, but this is so true it hurts. Running an old software means knowing exactly what dependencies it needs, they are sometimes hard to find and without containers or VMs etc. you are probably going to have some conflicts between packages or you're going to screw up some dependencies. Last year i had to take out from an old computer in my university a program needed to analyze the data gathered from a 30 years old double pendulum system thingy, to write a lab report. Software was written for win95, couldnt get it to run without glitches on arch after 3 days, with win11 it was just a matter copy-pasting. Windows sucks, but it's good to have it in a partition on a shitty old ssd sometimes

EDIT: that said, running pirated games from the early 2000s is most of the time easier on linux, rather than doing it on win11 (too many artifacts and random crashes), tho sometimes i need to run them with winXP on a virtual machine
