He is on paper but he's not responded to the teams emails in months and months. As I said, the only people left (and running this company now) are the engineers, with little money. Yifu ran off to to work with the government about anonymity and took the millions with him.
He is the founder but he isn't the only owner.
From my experience, I also believe that Yifu is no longer an active member of the Avalon project. The communication(s) and way the project has been moving forward is much more in the manner that ngzhang ran his FPGA project than how Yifu ran the Avalon project in the early days.
