It depends on if the first guy is complaining about having to reinstall this specific software, or if the software borked his entire system to the point that he has to reinstall his entire OS. Because that happened to me once. But in the first scenario he is being a dick, and in the second one not so much.
I didn’t say anyone owed anyone anything. I was saying one level of frustration was understandable, one was not. Anyhow, my case happened twenty years ago when creative commons barely existed.
