I trust Apple more than any party in the world. Even the government. Fortnight devs, Epic, whatever are not even on the same radar. They'll sell your privacy in milliseconds if they can get 2.5 cents for it.
I would never ever own an open source phone. Not because the operating system is open source (probably good that it has eyes on it) but there is no way to control third-party apps. Even the os builds can get hacked and I cannot trust it. I have so much personal stuff on my phone on it that I cannot afford to entertain Richard Stallman and his righteousness.
