Possibly the best write up of the Brock Pierce saga is covered here on Buzzfeed.
You have summarised much of it however there are a few errors like Brock settled with the accuser not his business partner. This immediately brought up the question who pays to settle a case for 20k+ when there is no legitimacy to the claim? Somebody well off and just wanting it to go away is a slim possibility.
My feeling is there is too much smoke for there not to be a fire!
As to EOS I'm a big believer in the team behind it and feel their involvment with Brock was a poor decision. It was not a decision that will stop EOS though just hurts their public relations efforts A LOT.
Personally I take one look at Brock Pierce and I think weasel. There is something not right there.
