Of course they didn't know what they were doing. It was written by a 19-year-old in the mid 90s. The code is messy with poor licensing and some build tools were included in the repository and they wrote a dumb license for it? Who cares, they shipped a product that 10s of millions of people used and loved and wanted to share that code up to the world and instead of embracing the best of what they were trying to do while helping them to make things better, the community piled on them until they said it was so not worth it that just pulled the whole thing.
Bravo and job well done.
