What if _you_ didn’t? I outlined scenarios which are real risks for millions of people and a fair fraction of those either involve no or limited user consent. Maybe it’d be possible to have a secure factory reset – this is harder than it might seem with firmware in so many places – but that only helps if you even know that you need to. Anything which allows undetectable rootkits means that a large number of people will never even realize that because phones are general purpose devices and most people are not security experts. Worse, how many of them are actively being betrayed by trusted experts - abusive partners, unethical technicians, etc. - who will say it’s fine?
