Generally agree with the ease of contribution sentiment to OSM, but your characterization of Firefox contributors dismisses the valuable work that 9 out of 10 Mozilla contributors do who aren't programmers. You absolutely do not need to be a good programmer, or any kind of programmer at all, to contribute to Firefox. https://www.mozilla.org/en-US/contribute/
To contribute to OpenStreetMap, you only have to know somewhere. It's quite likely that almost everyone knows something that isn't in OSM.
Even 2 people from the same town, but live 1km apart could probably contribute different things to OSM.
Combine that with everyone wanting to see their own town/city/house/area on a map, and it's a recipe for explosive growth.
