Business model: more on Red Hat

Few days ago I wrote a commented a Billy Marshall’s suggestion telling I was convinced was taking advantage of commons-based peer-production, and the difference between Red Hat and Oracle expenditures on R&D had a simple explanation.

Today I read Savio Rodrigues post, comparing Red Hat’s SG&A spending to similar data from IBM, Oracle or Microsoft and I got a clear picture of the (often) unseen side of the moon.
I think he did a very good job searching around SEC files.

And I’m happy he is also half convinced that proprietary enterprise vendors spend 5-10x more on sales and marketing. As I wrote it’s true that COTS open source software is found by users, but it’s not trivial to turn them into customers.
