I'm not a published app developer, but even if I don't trust Apple hundreds of millions of users do. If I wanted to market to those users, or if I worked for a company that wanted to, I would have to suck it up and deal with Apple and their platform in order to reach the users.

Not a useful question.

Also, trustworthy people do not ask you to trust them.

I am honest and trustworthy, and so if you gave me the pin to your debit card to go buy something for you, I would not mis-use that information.

But because I am honest, I would never ask you to trust me with your pin. If we were standing next to each other at a pos, I actively look away when you start to type so I don't even find it out by innocent accident.

Honest people take the trouble to figure out some way to get a job done without requiring you to trust them, even if you would have, even if it's less convenient for you both.

In fact, I think that one thing is probably the single biggest proof of trustworthiness.

A person or organization that I've never met before and and does not ask me to trust them, is more trustworthy than one that I've known for years and have a long history of good interactions with.
