There seems to be multiple different explanations of BU which is leading to some confusion.

Aquent has posted his reply to Adam's thread-opening post:

Bitcoin Unlimited instead proposes that node operators configure their own limit in a simple GUI menu. Currently, as there is unanimous agreement for a 2mb limit, the miners just sign their blocks with 2mb so communicating that they are willing to accept 2mb blocks. Once 90 or whatever % of them agree, then the miners can create the first 1.1 mb block and wala, we have a new limit.

Is this a hypothetical "unanimous agreement for a 2mb limit" of the miners or just BU nodes? So BU takes queue from a miner "BIP100 like" vote and combines that with a supermajority BU node vote to determine a new maxBlockSize limit?

That would only work if 51% of them so decided and, as we know, if 51% of miners decide to fork off they can do so currently.

Thus a simple majority of miners is the "BIP-100" like vote that would permit an increase if the corresponding nodes agreed?

The miners are self interested economic actors and we can assume that 51% of them will be honest (if we don't make such assumption then bitcoin does not work).

My thoughts are bitcoin simply made the game theory incentive to merely discourage dishonesty by incentivizing miners at a greater degree to secure the blockchain than attack it. Why are we assuming honesty? I hold the opinion we should prepare for dishonest and malicious miners as a possible attack vector. This is why we need to focus on decentralizing mining much more.

Right now for example we have core stating 1mb or bust - well there is unanimous agreement that approach is wrong and the limit has to increase to at least 2mb because businesses right now are hurting.

Is this true? As far as I know only Luke-jr wants to keep the blocklimit or lower it. Peter Todd signed up to make an effective increase and the rest of the scaling signers want to raise maxBlockSize after all the other improvements are completed to accommodate the LN. Is this simply a misunderstanding because I repeatedly see this being repeated on that forum and on r/btc or do you acknowledge cores statements and are assuming dishonest intent?
