A prior time he did this was with GrapheneOS which ended in tears when he had epic fallout with the primary maintainer and withdrew all support because.. no surprise.. all the security of that fork is in the pocket of a single individual who may or may not, as according to Rossmann, be stable any given day of the week.
We all make mistakes and I hope he will retract if needed but the attention economy is clearly an -attention- economy, not a truthful-content economy..
