This is a good write-up.
In addition to this issue, I've also had good conversations with a business owner about why he chose a Windows architecture for his company. Paying money to the company created a situation where the company had a "skin-in-the-game" reason to offer support (especially back when he founded the company, because Microsoft was smaller at the time). He likes being able to trust that the people who build the architecture he relies on for his livelihood won't just get bored and wander off and will be responsive to specific concerns about the product, and he never had the perception that he could rely on that with free software.
