I totally agree with you, and I think the simple explanation is that it starts at the top. You're building software with Microsoft tools on Microsoft platforms. You're in "commercial-land" right out of the gate. You're probably building software at a big company, or for a big company. Paying for software is common, and not a big issue. The cultures are just different.
It's not a reflection of the quality of the software or the quality of the engineers - it's just a fundamentally different culture.
