I suppose it's all open to interpretation, but basically he was writing posts that, while "valuable" didn't seem like they should be getting $400 each. It was just posts about different crypto performance in the market. And he was doing this 5-10 times a day, and making that amount of money each time. And it was all due to 1 whale upvoting him every time. So...as you can imagine this looks pretty bad (no one person really deserves 6% of the entire rewards pool every day). And then him and Bernie Sanders (the account, not the actual person, lol) got into a spat about it...and so on...
Not sure what's going on with the truce. I heard there were some stipulations between him and some witnesses, but it's all beyond me. At the end of the day it's all just a good representation of how the current system is overly beneficial to whales who got in early, and it's hard to properly correct it at the moment.
