The day before wjz304 decided to stop his work, someone reported a new issue on his GitHub and asked why modules were not open source on his repo. There was reference to something that was named "secret". You could see it called out in the code.
I didn't see what wjz304 responded to him, but that seemed to upset him to the point of leaving the scene. I don't want to believe wjz304 did something malicious, but he immediately closed everything and said he was accused of not disclosing driver source code. It was an extreme reaction.
I'm hoping @wjz304 could expand more on the topic since the question seemed fair.
