I like to be thinking that, but being aware of me liking that thought, I'm asking myself: would I actually do so being some Apple executive? And I'm not sure I would. I do think that being community-supported is really, really great, and OSM has a pretty good community too. I'm a big opensource proponent, so it's easy for me to say, but I also think having their maps (software and data) free (as in GNU, yeah) wouldn't harm Apple, given the map is not their unique product they are selling. And being a native supporter of something that could be wikipedia for maps would be huge. So, yeah… yay OSM?
But, with all that said: IMO, OSM is a huge organizational mess. Giving them money & satellites, and then just expecting it will all "solve itself out" isn't really something I would do being responsible for Apple Maps. For starters, it's not like all OSM community members automatically become Apple employees, you're basically donating to somebody over whom you won't have any leverage. What's more important, it's not clear what it the goal of the donation, what OSM is expected to do with that? And how it will serve Apple? Their priorities seem to be quite off, OSM doesn't give a shit about any "product" whatsoever, they are just guys passionate about collecting all sorts of geo-data into databases nobody ever uses (at least, as far as OSM is concerned, they are the database: they don't make apps). And it's even questinable if such way of collecting data is the way to go in the age of imaging satellites, widely accepted spyware on every phone, ML and "big data".
And it's not like this is cheap, any way it would be done. And, no offense, but "partnering" with OSM wouldn't be exactly partnering. OSM doesn't have managers, engineers or cartographers any better than Apple can hire, all they have is community, which wouldn't even be OSM community anymore, if Apple rolls out a better (and more accessible) open geo-spatial DB than OSM has. Which, I believe, they are capable of.
also Apple need to bring alternate satellite image providers like ISRO, SpaceX
I think a perfect example of Apple doing this is: Webkit. Webkit gets back a lot from Apple (though I'm sure there's plenty of room to be miffed at Apple for being slow sometimes, but it still doesn't disprove the point) and it's a core part of their user-facing applications.
Personally, I'd like to see them just open source what they have and let the world enjoy. Either approach would certainly remove the death grip Google has on mapping solutions right now.
