Well, you nailed it, again :)
There is a generational divide here. People like Karl, who were around when we created these licenses, know the ethos and values behind them. To that generation public licenses were a vehicle to “hack” ownership law, to create a sustainable way to give things to the public.
For a long time, part of the barrier to entry in being involved in open source was internalizing that ethos. As we’ve lowered most of the barriers to participation in the “GitHub Generation” we also removed that one. I think that this is a good thing, it means more people participating in open source, but it does have some other consequences that you’re seeing play out here.
The sense of ownership to the community, rather than to one’s self, isn’t necessarily shared amongst open source participants the way it may have been in the past.
