TTN V2 to The Things Stack V3 Transition

Well, ‘Make owner public’ - owner is at least how this has been presented to users the last 4+ years.
The ‘owner’ was previously also displayed in gateway details on The Things Network Map (but not anymore lately).

What was (hacky) owner in V2 then?

Is it just me or is that contradictory (confusing at least) with the previous quote?
