That’s like asking a spy for evidence of their current mission.
Does the spy’s denial of knowledge or a lack of evidence of that spy’s mission mean that individual was not a spy? Quite the opposite. It means they were an effective spy.
This isn’t enlightening. It sounds like there is no evidence and the user to which I originally replied just wanted to besmirch the reputation of the Wine project without a good reason why they are lying about rejecting legally troublesome contributions. It is possible to go about an open source alternative honestly.
