Because 1) I work on an open source project as part of my employment, not for free on the side and 2) If there was no cla, most likely the source would not be open as the project wouldn't want external contributions. That's strictly worse. Also, the types of contributions that the project would ideally see are mostly from other companies, not people working in their free time, so the cla doesn't really discourage contribution.
