You should be wary always. CLA or not, nothing guarantees that the project you depend on will receive updates, not even if you pay for them and the project is 100% closed source.
What you’re suggesting is perpetuating the myth that open source means updates available forever for free. This is not and never has been the case.
Was I, really? Maybe, if you feel so... but I'd have to say that I had no idea.
What I'm suggesting is that a FOSS project without CLAs and a healthy variety of contributors does belong to the broad open source community that forms around it, while a FOSS project with such CLA is just open to a bait-and-switch scheme because the ownership stays in a single hand that can change course at a moments notice.
Whether the project stops receiving updates or not, is an orthogonal matter.
