Entire companies and (worse) government depending on a single vendor knows for it’s 30 year long history of attitudes like “we before our customers” and “well tell you anything to sell you, but well barely do the basics on our products” and"we’ll make sure we’re compatible with nothing, going as far as sabotage, so you can’t escape our greedy claws" is a very bad idea ™. Forcing customers and citizens to use that crap is even worse.
With Linux ( and the open source world) you have an open System that has been independently verified by millions, you have actually inter system compatibility oozing out of the wazoo. You have vendors selling software that you can actually rely on.
