Because monocultures have always been good for development and progress.

I didn't say "wipe OSX, iOS, Android and Windows from the face of the earth". And Linux itself is sooo far from a "monoculture".

So many challenged people over here. I only said (my opinion) that humankind will be much better of if you use and improve something, but you insist on seeing something else. Do yourselves a favour and have some deep introspection folks, cause lots of people get in trouble for hearing and seeing things that are simply not there.
