@amgine @Wuzzy If you have evidence of Google Maps incorporating OSM data, please contact the Data Working Group: https://osmfoundation.org/wiki/Data_Working_Group#I.27ve_seen_a_problem.3B_what_should_I_do.3F (their emails in a paragraph there). They are absolutely not allowed to do that.

My exemplars are dated; some years ago I was adding cemeteries to OSM in order to show them in my genealogy project. Within a half hour they would appear in Google Maps, and I could compare/contrast the satellite imagery and possibly edit further.
Likely I could test with the same process.
