This is flat out wrong. Many engineering positions do not require a PE certification or state licensure. For example, consumer products are mostly regulated by liability and testing regimes like UL/FCC as opposed to stamping a design to assert that it meets the requirements. Engineers designing consumer products are still engineers.

I agree that the profession of "software engineering" could stand to have much more of the rigor of engineering. For example, it's painfully missing a sense of ethics about large scale surveillance systems. But your argument is biting off way too much.
