There's kinda two audiences for this paper: Uber, the engineering team that migrated away from psql, and the tech community at large, which saw Uber's technical decision as a signal about the quality of psql. IMO, the shrug emoji is fine. If it were the only response, that'd be a problem but the author gives a proper response in the following slide: it was a short lived bug, and it's not like MySQL is objectively better. I can think of a few MySQL problems I've run into, like fixing a data loss bug in the rollback code by refusing transactions larger than 10 percent of the rollback buffer until a real fix can be published, making backups, restores and migrations pretty much impossible. But the tl;dr here is that psql will continue to get a black eye in the tech community as long as slony exists and is useful.
