>This dude set up a "this is for free" sign and then some other dudes just swooped in saying "we'll take all of this" and then just replaced the sign with "$500k".
This loses the important nuance that them swooping in and slapping a price tag on their own use of the implementation doesn't deprive anyone of access to the original on the same terms they were able to access it.
No one has lost anything in this scenario.
>The problem with this is that it disincentivizes the sharing mentality.
Personally, I feel arguing over how people make use of freely shared knowledge does more harm a culture of sharing than usage of said knowledge, even when that usage pushes right up to the bounds of what is allowed under whichever license.
