Question: if I contribute a fix to Google Maps or Apple Maps, does that fix back-propogate to OSM? My home address needs to be slightly shifted and wondering for best practice.

No and that is IMO the point of using OSM in the first place. The data is public and free for everyone and if you contribute there's the possibility of other services adopting your change. I know that mapbox integrates osm data, Google and Apple might too.

No, in fact copying from Google Maps is a violation of their terms of service:

If you contribute to Google Maps then you fix private Google database.

this is not true, you fix it for everyone using Google maps (which is basically everyone)

Where I can download Google map data dataset for my own processing?

Yes, Google makes apps usable by general public but their database is proprietary - including what people contribute for free.

ok I thought parent comment meant to say it only changes your private maps, not for everyone. I see what you mean

The argument that OP may or may not have intended is that any change in Google Maps benefits a fraction of “everybody” that equal to Google Maps’ share of the market. That’s maybe 80-90%. Telling users of Google Maps that their contribution is worthless if they don’t submit it to a free & open database may be net-negative if only a small fraction gets discouraged from contributing altogether.

I have a few million edits on wikidata to proof my sympathy for Open Data. But the openness is only useful if it leads to more people having access to the data. And a proprietary service being involved doesn’t diminish the value by itself.

The answers saying “no” are not necessarily correct, but the actual answer depends on which country you live in.
