Editing OpenStreetMap isn't quite equivalent to commenting on a post. OSM allows you to edit anything, which is fantastic but also allows for more serious vandalism. We have seen major cities renamed to racial slurs, for example. As with Wikipedia, the community is generally very good about correcting these issues quickly. It's an uncommon problem that a lot of people work to mitigate. But I stand by what I said: vandalism on OSM is in many cases unacceptable to show to end-users.

The OSM basemap is used in many official publications, in many social media applications, etc. I'd actually recommend using the basemap for most simple mapping cases, as long as it's being continuously updated from upstream (or, it is the upstream basemap). If you take a snapshot of that data, however, you risk capturing some bad stuff. That is a real risk for a company like Meta.
