Publicly accusing Henry of not actually working on the project seems short sighted. Only looking at a one year slice of contribution rather than the lifetime of the project masks the full picture of Henry's contributions. Also in Henry's defense, the past year has been a terribly difficult one for most all of us to get through this pandemic.
Not a good look for you Sebastian. Feels like you are looking for a place to point blame and unfortunately decided to direct that blame in Henry's direction. Henry Zhu is a great developer and contributor. Really deserves better than this.
