I agree it's harder now than on steem and did make it a point to show that it's fairly easy to break away from a successful attacker- and I think most reasonable people would think it's fine to recover a social network in this way.
But making problems more unlikely doesn't eliminate them, and to date PoW is the only system that can recover from these events without a human, and on top of that you need home users to be able to run their own sovereign full node on as little equipment as possible to achieve "full" censorship resistance & immutability. 51% attacks are mostly just inconvenient. You are supposed to wait 6 blocks for finality on btc, technically
I also agree that the tradeoffs DPOS makes in these areas are fine for it's use case. This is a great platform for a social network and people should use it. It's just not the kind of thing to put your life savings into maybe.
I think we disagree on how easy it might be to socially attack DPOS validators. I have been watching every major US brand, tech giant, social media platform, cable news and newspaper launch a coordinated assault on democracy for the past 4 years. But even this is easily forked away from more cheaply than it would be to pull off. Hive is a very powerful weapon for speech.
