Well, FOSS is free (also "like beer", i.e. unpaid), so I don't find it surprising that it doesn't follow commercial mindset priorities. People working for free are driven by other motives. While needs of commercial users would be considered and accommodated in many cases, they are not the only priority, as they would be for a commercial enterprise like Microsoft.

I think you are pointing out the conflict that can then arise, but that I don't think is avoidable: a company has relatively short-term aim of surviving until year-end (or quarter-end) and making money. FOSS contributors are hoping to create something worthwhile by whatever value system they adhere to (elegance, public recognition etc).
