I think it's a lot more important to decide who you want to trust.

The problem is that there are a lot of small apps that end up being scams. Or they end up selling their software to scammers. Or they just don't have the ability to properly secure their system (LastPass).

Apple has kind of made a name for themselves as a big company that cares about privacy and is serious about security. And they don't have the reputation for totally screwing over their customers randomly like Google.

I can see a lot of people making the pragmatic decision to just keep trusting Apple instead of figuring out which other company to trust as well.
