I think I actually prefer CLAs most of the time. If I’m submitting a patch to some piece of source available code it’s usually because I encountered a bug or missing behavior that is getting in the way of my work and I want it to be fixed. I just want to give away my code; the last thing I really care about is getting an email from some lawyer years down the line.

Now if I’m signing up to be a core contributor/maintainer of a project and you ask me for a CLA then I take issue.
