I think the way in which we could do better is to all stop making excuses for @faddat's unwarranted tantrums and mudslinging.

The code is there for him to review, and all the demands he was making could have been resolved by him taking 5 minutes to read it. (He even had three experienced devs helping him in the comments in the linked thread.)

Instead, he chose to (in order): assign blame, be passive aggressive, play the victim, and then speculate about malice—without basis. We are all now aware of how productive these behaviors turned out to be.

He shouldn't have to speculate very much more to figure out why he is unwelcome in our Slack.

We welcome constructive feedback, positive and negative. This wasn't that.

We are a very small team and reading and responding to this sort of toxic behavior has tangible effects on our productivity.
