Frankly, I think that is a situation where Microsoft just voiced what was common practice in many places in the industry. I've worked on a variety of both commercial and widely-used open source software projects and in all cases, GPL-licensed code was forbidden after consultation with counsel because of the limitations it would have imposed either on the company itself or on the users of our software.

This is more due to bad lawyers not understanding things than gpl itself, especially considering agpl, apache2 etc. Usually because nobody takes the time to explain it to them. Using RedHat as an example tends to be the most productive with legal and the C's in my experience.
