I'd be curious to hear about this too - I don't see any issues filed or commented on by him, perhaps the bugs are more perceptual mismatches with his React experience as opposed to actual bugs. We only recently released preact/debug, which brings with it some of the guardrails React ships by default - maybe without those people run into issues.

FWIW there are hundreds of companies (some very very large) using Preact in production. If there were showstopper bugs, they'd be fixed immediately.

I think this may be referring to "preact-compat" issues rather than Preact issues. I know the Inferno team recently had to change a lot of the state scheduling to be 1:1 with React 15/16 (i.e. batch sync schedule setState after events was very broken and there were issues with controlled components in Safari).
