Here in the US I'm pretty sure they are using NHD data for water
features. It definitely isn't OSM. Any similarity to OSM in that case
probably means that patch of NHD was imported into OSM as well. The
roads around here are almost certainly TIGER. I see some of the
same... "special" ... features that I have long since fixed in OSM.
Hard to say if it's TIGER->OSM->Apple or straight TIGER->Apple though
since I didn't make my first edit until April 11th, 2010. I don't
remember a gaping hole in this intersection though:

Yes, it is OSM. Look at the layout of the footpaths on that green/open area in the Portsmouth example.
I actually remember surveying that as part of the Portsmouth mapping party a couple of years ago... There are other footpaths on that green area which I didn't get time to do. And they're not on the map. ;-)
Oh yes, it's OSM. I've been mapping a lot of forest tracks in my
neighborhood  and indicated some tracks that I didn't walk with only
a short stub.
Apple has all these stubs.
It also has all the local names that Google does not have and that are
a combination of dutch AND data, BAG data and local knowledge
Also in a different region  Apple has exactly the features I drew
and which are not in Google.
No way that comes from a different source. It is OSM.
The data is quite old though. I would think at least before last
