There's also the ability to collaborate with people who don't have an iOS device. If someone creates a Collection in Apple Maps I just don't get to participate. If someone creates a shared list in Google Maps I can see it on my phone, a web browser, someone with an iPhone...

And Google gets to see it too. And all their advertisers.

Google doesn't give your map collections to advertisers.

It's true that Google gets to see them, but Apple is no better in that regard: they store your collections on their servers too (where else would they store them?).

Apple is better in that regard.

End-to-end encryption

Maps keeps your personal data in sync across all your devices using end-to-end encryption. Your Significant Locations and collections are encrypted end-to-end so Apple cannot read them. And when you share your ETA with other Maps users, Apple can’t see your location.

Other useful sections on that page worth reading: "Location Fuzzing", "Random Identifiers", and "(on-device) Personalization"

_SHARED_ collections between multiple Apple users are not E2E encrypted.

Don't spread misinformation on privacy, it'll mislead people into sharing too much data.

That’s interesting. Can you point to a reference for that?

I would have assumed that shared collections with a group of iCloud accounts would be e2e encrypted like iMessage groups are e2e encrypted. Glad to revisit that assumption.
