Why do you use Linux?
For me it comes down to:-
Cost It’s free!
Freedom I can do anything with my computer when it runs Linux. If it breaks, I can reinstall it without a problem (no need to find a product key or anything as archaic as that). If I want, I can try a different distribution. There are no limits.
Privacy and EULAs No end user license agreements and no snooping by big corporations. I can and do install Linux on as many machines as I need.
