In the past there was lots of incentives to change to Linux, but today it isn't worth anymore.
Today if Microsoft breaks Windows in some way, user will blame Microsoft and pay you to try to fix it.
If you recommend Linux, they will blame you when developers remove or change some feature they need,then you will explain it is not your fault, and then they will want to pay you to fix it, and then when you explain to them you cannot fix it because it is not worth and even if you could, devs would break the system again in the next 6 months, they blame you again and ask you to reinstall Windows.
