Right, I see what you mean, but that's merely “saving the company the hassle of bogus support requests” and still has nothing to do with the claimed “improves reliability and consumer safety”. This actually confirms my intuition that the safety argument is BS (as always with this argument).

And even from a “bogus support request” PoV I fail to see how opening up your product degrades things, as the risk of a user having an issue with third party components should be lower, not higher, if the said components don't have to hack around proprietary restrictions.
