I know this is a joke comment but Linux is for sure an enterprise kernel first and foremost. It did not start that way but that is how it has been developed and managed for many years now. Maybe the most incorrect thing anybody has ever said on record in the computer industry is when Linus said Linux was “not going to be anything big and professional”.

Linux distributions, which are conceived and managed totally independently from the kernel are available for every niche. Many of them are desktop and “consumer” oriented. With many Linux distributions, I would say that it is more accurate that they are hobbiest oriented more than what Microsoft would mean be “consumer”.
