Earlier quoted context omitted.
If you come at it from the perspective that Google is your friend, as in not like a real friend (who I wouldn't let change my passwords), but a friend that's even better than a real friend, then sure, these points are paranoid. The GNU perspective is very distrustful of the idea that anyone else should be administrating their devices, and refuses to trust any corporation more than they would a friend.
GP's points still stand, if coming from the perspective that Google is a successful, multinational corporation, with a reputation to protect, and staffed with thousands of engineers who also have their own job standards and individual reputation to protect.
- Multinational corporations care little about their reputation - the public has very short memory, and it's rare that a reputational issue outweighs considerations like sunk costs, network effect, or lack of better alternative on the market. See literally almost every scandal involving a corporation ever.
- The larger the organization, the less individual ethical and reputational concerns of bottom-line workers matter. See literally every corporation. For particular recent examples, see e.g. Volkswagen emissions scandal or Boeing 737 Max fiasco, both cases involving actual engineers with actual careers on the line, and not just software devs risking unemployment for 10 minutes.
Note that both statements are explainable even without attributing malice to any corporation. They're side effect of scale and market power.
