As a long-time OSM contributor, 1 is the only one that bothers me. We've had a bit of an issue in the UK with Amazon Logistics mappers blatting away some of the nuance in rights-of-way mapping (which is quite a complex subject in UK law) as they map driveways for their own use. That's not a massive problem in itself - OSM has reasonably good communication mechanisms (particularly changeset comments), and there's a clear Organised Edit Policy which most of the big guys follow. It's just a challenge because of scale: it's hard for part-time, unpaid volunteers to spend hours chasing after the countless Amazon contractors who are sitting editing OSM all day. I know we've lost a few individual contributors because of this, though more in the US than in Europe. But this is mostly growing pains. With goodwill from all sides I don't see any reason it won't be resolved.
