What does HackerNews think of OpenPDN?

Paint.NET source (v3.36.7; prior to non-MIT license change)

Language: C#

Paint.NET was open source (MIT) until 2009, alas nothing happened from the forks after they changed the license.

Code is still available, not sure worth building though in 2023 when there are other options

You can still get the source code for paint.net before the license change happened here: https://github.com/rivy/OpenPDN
Paint.Net used to be MIT licensed. I don't really know why he went back to closed source but I saw a comment he wrote where he said that releasing the source brought him only misery. Does anyone know any details about that?

For anyone interested, the MIT-licensed source is still out there: https://github.com/rivy/OpenPDN
