I think we can proudly advertise that LilyPond runs on all common
operating systems, I personally invested quite some time to create
that. This empowers users who are for one reason or another still
stuck with a freedom-denying operating system.
I think it is wise to have some awareness about it when saying how
fantastic the experience is of using a certain piece of freedom-denying
software.
