https://news.ycombinator.com/item?id=42253494 - flagged my heavily upvoted comment, tptacek (founder of fly.io) appears to be downvoting comments critical of him.

"I'm really shocked at the unprofessional damage control on display here, tptacek is downright belligerent and even going to insult people for wanting reliability from a cloud provider.

Instead he doubles down on the long history of unreliability and downtimes with immature retorts and word plays.

It's unfortunate, I've given him a chance to explain but he repeatedly goes on the offensive and extremely condescending to people who naturally are dismayed by fly.io's recorded history of unreliability."
