Proven but unlikely. Linux on the desktop is still not a thing the masses will adopt, despite all the times we hear that someone put Ubuntu on their grandparents' computer and it turned out fine.
Once you get to a higher bar where people do need to install software, Ubuntu loses that audience (because they wouldn't find the software they expect to)
You have some nice customers! I was lucky to join a company that allowed me to choose linux as OS, the previous company strictly refused. I'm strong on Linux, but I won't lie that sometimes things are pretty rough, even with widely supported distros (Fedora, Kubuntu)
