And improving OSM _feels_ great in my experience. It's actually and primarily helping the open-source community.
Google really incentivizes users to fix map data (like business info) and, after doing so, shows you popups like "Your change was seen by 10,000 people!". Really good UX. Yet, I was only doing free work for a mega corp which doesn't feel as satisfying (and I stopped doing so).
My feelings exactly. I first got drawn to editing OSM instead of Waze because of local Waze volunteers acting like mini dictators (locking the map for people under a certain level, leading to inaccuracies like wrongly labelled construction in my own street which I could see with my own eyes but could not edit), not being an unpaid worker for Alphabet was a nice bonus and the reason I stayed in the long run.
