I've been a swe at big cos for 10 years and I believe this because that's literally what the lawyers repeatedly informed me was the case. Every significant launch involves a moment where a senior engineer meets with legal counsel and explains the launch and counsel says if they see legal risks with the launch. It's also routine to meet with them early and discuss possible future directions or explain the business value in revisiting a standing policy to see if the benefit to risk is worth it or not.
If you're saying that random engineers aren't actually entitled to meet with legal counsel and have a privileged conversation where they privately ask for directed legal advice, that would be surprising news to me.
