All philosophies are inconsistent?

That's not a paradox. Binary blobs are okay if, and only if, there is no way to update them anyway. This means there is no way for the copyright holder of the software to force a user to cede their software freedom, so the point is moot.
> software should be libre because libre software provides the most value to the most people due to the 0 marginal cost of software
Software should be libre because it allows users to not be beholden to anything but their own interests. Value and cost are very secondary considerations.
> even if it's less profitable to the creators
That's not a criterium.
> due to the security benefits of closed platforms
Citation very much needed.

No. He was working, at MIT, you just stated that.

I think you might want to get better acquainted with "his philosophy", the economics of it, before diving head first into an argument based on nothing but ad-hoc analysis of shaky assertions.
Apple’s business model also aligns with user privacy (so far).
It’s also worth considering Apple’s CEO personally values privacy because he had to keep his sexuality a secret his entire life until he reached such a prominent position he felt safe to speak out.
I agree that the strongest evidence is the source code, compiler code, and electronics schematics. However, there are other forms of evidence.
The other (perhaps more compelling) argument is that Apple is only able to invest this level of security in its products because of its spectacular profits, which would likely be much lower if iOS were open source.
That's basically the gist of it.
EDIT: To whoeever downvoted this, I'm just relaying the argument.
The only difference between universal food and universal toilets seems to be the cost - i.e. it would be much more affordable for government to supply free toilets than free food for everyone. In this view his argument makes sense - both the need to eat and the need to pee when in public are fundamental, so if we can take care of at least one of them (toilets), then it's still better than nothing.
