Linux is running on the majority of servers worldwide. Even Android, the most popular mobile OS worldwide, is based on a linux kernel. The attack vector is already there, there are billions of devices running linux out there, so it’s not that you are using some obscure operating system.

TBH: Most private users aren’t really using many programs. They are running chrome. Maybe an email client, but even that is declining. They are looking at pictures with the standard photo viewer and maybe at some PDFs and sometimes they are writing a letter and print it? Linux totally can do that.
