Small correction, but a CLA is a contributor licensing agreement, not a copyright assignment. The contributor still owns the copyright to their code, they've just explicitly allowed the project to license their code under the terms of the project license.

Depends on the CLA. Many CLAs (for example the one that RoboVM used that allowed them to switch their GPL licensed compiler to a closed source model more easily) do require copyright assignment.

I've fixed it. There are various models, CLA, assignment, etc. I didn't want to get into details of that.
