Different take from a coder.  Hard to judge before you've walked 1km in someone's shoes.  Did you see how much code they wrote.  How difficult the things they were trying.  How much progress.  Hell even the mutinty faucet was used all over the place for taproot, because after 13 years the whole of bitcoin could not make a working testenet (tho that is fixed today).  Most important:  have some empathy for burnout.  Its a really hard thing, especially in software development.  Ok, maybe you have seen it too, or 10x worse.  It's honestly a horrible thing.  Maybe you dont like his tone, and that's OK.  But I think he's one of the good guys.  I might be wrong.
