I don’t disagree. How I think it will happen: Backwards compatibility will start to stray at Microsoft (their last bastion), leading to WINE becoming the go to tool for backwards compat support. Microsoft will create a linux variant or maybe just a DE and the rest will be history (just as Libre Office has begun to supersede MS Office). It is a matter of will and time that C-Suite will want to eliminate labor around Windows to maximize profits as it becomes more and more hardened in it’s feature set. Why maintain when you can utilize FOSS?
