You are generally right. Mind that this (commercial OSes) is on an entirely different level. However, I'm afraid, if there was a way to effectively commercialize FOSS software, it would have gone the way of e-mail or Usenet. Regarding iPhone (and smartphones in general), I'm with you. However, I don't think that this ill-fated CSAM filtering attempt was meant to establish intrusion. At least, if I was Apple, I would go a long way to avoid becoming a transparent tool for law enforcement and intelligence. There is no win down that route, only pain, lots of pain. They are doing fine without it, already.
