This is true, but it's also potentially worthwhile to consider that Apple has positioned themselves as a hardware company (i.e. the majority of their money is based on selling units of hardware), whereas their main competitor here (Google) is an ad company (i.e. the majority of their money comes from selling their users' data). Apple has chosen to highlight their commitment to privacy partially because they feel it helps their market position, whereas for Google, it would hurt it.
Certainly it doesn't mean that Apple is infallible, just that I think it makes it easier to accept that Apple is more likely to protect privacy more than Google.
I'm pretty biased towards Apple, so obviously this may not work for everyone; if you need source code to feel secure, then by all means, go for it. For people who are looking for less work but some of the benefits, I think that Apple is a decent way to go.
