some kind of genuine software engineering certification
That only gives those in power another way to push people into toeing the line. There's enough corporate authoritarianism these days as it is already. Give Stallman's "Right to Read" a read. His dystopia is exactly where we're going to be headed quickly if we keep demanding someone to "do something".
"The optimal amount of fraud is nonzero."
"Those who give up freedom for security deserve neither."

FAANG, Fortune 500, etc., almost universally go out of their way to violate user freedom in pursuit of profit. Regulation is practically the only way to force megacorps to respect users' rights and improve their security, as evidenced by right-to-repair, surveillance/privacy, and so on.
And none of that has anything to do with users' individual rights to create, run, and modify their own software.
