Google indeed has RAPPOR (and other projects, I'm sure), but the cultural difference Apple claims is "we consider privacy in everything we do" instead of "we add privacy where we can."
I'm pretty sure that should be interpreted as "we've determined privacy is a differentiator in the market, so as of some indeterminate time in the past, ranging from a few years ago to our inception, we consider privacy in everything we do."
Now, there's nothing wrong with that, and that's not to say they haven't been privacy conscious in the past, but let's not confuse the current stance as entirely altruistic, when there are are multiple incentives at play, one of which is concern for the user.
Edit: s/months/years/, that's much more accurate.

> His comments arrived as Apple started to identify Google, and its ascending Android operating system, as its chief competitor. Here we see the first signs of the hardware seller deploying its privacy position as a branding and competitive tactic, a strategy that has come to the fore during its current standoff with the feds.
What a bummer!
Like I said, there's nothing wrong with this. We just need to be sure we don't fall into the trap of thinking we can take what is presented at face value as the whole story, just as you can't when dealing with individuals much of the time. Apple is not our trusted old friend, that will look out for our best interests. They are at best an acquaintance that we have a business relationship with. That doesn't mean they won't act in a manner we appreciate, but it does mean we should not assume they will act as a good friend.
Theses devices are never on the same network, the only shared parameters is an exchange account. As a rule I always log-out of the only Google service I rarely use, so this must be some cookie/tracker dark magic.
Sadly I have no proof, but I use gosthery to block trackers since then. (Side note: gosthery also claim to use DP btw)
But this is not how privacy should work, cause there is a lot of people out there that don't read HN and only recently found out that there is a lot pastry inside their computers.
1.Collect personal data, send them to mainframe, use them to profile and deliver custom tailored services. When sharing hash so that individual records can't be extrapolated
2.Collect personal data, use them locally sometimes using mainframe provided 'models'. Return to mainframe hashed records to improve models.
Google is clearly using 1. while Apple claim to target 2. (I don't think it's actually the case now because I though Siri actually store some personal data on the cloud so far)
Connections are a two way street. Facebook can assume that if he has connections to you, then you may have a connection to them.
Nothing nefarious is necessary.
