I think the main advantage of a Linux system is that we, the owners, would not be victimized by "updates" to the OS. Linux systems are extremely versatile in their modular composition, and a working system could be viable with newer updates through the proper interface add-ons, not having to worry about rank and file updates disabling other non affected support systems.
Pick and choose what parts are needing updates and the others stay working!
It is also an extremely efficient OS in its kernal form, and add-ons can be done piece by piece.
It could also keep dongles out of the equation as shareware plugs become better.
All that is needed is several years of trial and error, and if enough people are happy with it, it will support itself just as other Linux sites and programs are able.
Go Linux.
