I’m in total agreement that OSS builds more secure software. What I’m saying is that these companies are not in the business of building safe software.
From there, I see no advantage to closed-source here.
I think the easiest mental map is this: doing things well has a cost; doing things poorly can be cheaper; if it’s way cheaper and there’s some method available to de-risk it even if a little bit, no matter how little effective it is, it might be financially advantageous to pick the inferior option. This is not just for security, but pretty much everything.
