I’m a pretty junior contributor (I spent a couple years completing quests on StreetComplete and only have been adding new buildings, etc for a few weeks). I don’t know a ton about how the organization is run, so I can only talk from my experiences. I’ve been able to upload changes which will be live before they will be reviewed. I know there are reviewers who go through areas regularly, but they definitely don’t cover everywhere. I’m not sure if OSM has the ability to lockdown areas with frequent vandalism.
FTFY. Tesla is a tech company that makes cars. Their union busting practices are business decisions, which in turn affect the industry, which again, is technology.
