I've no one left to convert, my mums been running Linux since ~2016 when I got tired of her breaking windows (and in fairness it was her doing it most of the time) so I switched her to mint.

Her only requirement for her new computer is "it has to run that minty thing?" (it's actually running Fedora and has been for quite a while but that's the nice thing - she doesn't need to know or care) - it's still the same for her either way.

My score so far: 5 people directly, some ~40 workstations at my employer.
