The average user doesn’t give a shit about what OS they’re running. They also don’t know what tools they need. I remember a client who dropped $700 on Photoshop because “How else can I resize my photos?”
Linux is to hard for someone who doesn’t know why it’s bad to install multiple antivirus suites. People who don’t know the difference between a web browser and a search engine.
Linux will only ever be for hobbyist because they the only ones who give a damn.
