My take is that:
Linux is a utility OS. Just doing what you told it to.
Windows/Mac are a general purpose OS. They try to assist and help you where possible. But thwy allow for some kind of deeper tinkering if needed.

Linux trys to become Win/Mac but failing because of the fighting you mentioned. Also because that OS aint being checked by QA for general folks.
Windows Server/Mac Server are trying to be a Linux OS but being way too bloated and trying to do things they arent meant to do.
