These are all terrible arguments, sir. There is absolutely no way to make an argument that closed-source software is just as auditable or secure as open-source software. There will always be methods of trust required when you use things other people made, but when software is developed in a black box, with NDAs you didn't know existed, or 0-days known about for years, you simply CANNOT make an analogy to heartbleed. Heartbleed was one vulnerably in a poorly maintained OSS library. It is foolish to use it as your primary example of the failure of OSS security when there are tens of thousands of closed tickets on Github, Bitbucket and Gitlab to that would argue OSS is easier to audit and easier to openly discuss ihfosec issues.

By coming up with the same examples over and over again in lower threads you are coming close to trolling this thread and ought to stop and come up with a better argument for why a corporate system-on-a-chip system is inherently just as safe as hardware developed with open source firmware.
