Whatever marginal value they have as a signal of commitment is swamped by their negative signaling. Top caliber talent won't usually be certified; why waste the time getting "certified" by organizations that are probably less competent than you?

Successive rounds of adverse selection produce a "certified" pool of candidates who are unwilling or unable to achieve a basic level of facility in their field on their own, which is its own negative signal.

I agree with that basically. I've spent the last 10 years kinda being a "fixer" but mostly a network engineer. I haven't had time for any certs, I'm too busy working... When I have time for certs, who knows what'll be going on.
