It was a bunch of stupidity where spez doubled down on the price hike, then lied about being unable to work with 3rd party devs and how much they were "costing" reddit.
I thought his answers said a ton. I was on the fence about leaving reddit before the AMA. Then his answers convinced me that there was no saving the place. His attitude towards the community and 3rd party developers was absolutely atrocious and very telling about how entitled he felt.
