As a developer, I care a lot more about getting improvements back. GPL is massively beneficial from that orientation. That's why some commercial companies prefer GPL, because the developer of code gets stuff back.

As a user, I care a lot less for GPL, because now I have to publish my changes if I choose to distribute binaries. If I'm a user and I have MIT or BSD code, as a user I have a lot more freedom to do what I want with MIT code.
