I respectfully disagree.

The primary purpose of the GPL is to insure that users have the freedom to modify and redistribute the software they use should they choose to do so. Whether the user does so or not is irreverent. That's why I don't think it's a matter of whether end users care, or how large of a percentage they form of the overall user base.

Developers who decide to license their work under the GPL do so to safeguard their own freedom and the freedom of their users. To that end, I think the GPL hits its mark.
