I think, looking back in regards to XT, mistakes were made. Not because of anyone's fault and I don't think anyone is to blame, but it's just how things went in the circumstances. If we are to see realistically, XT has become a stale, old and tainted thing.
BU is the new hip stuff and cuts through. So far the other side has been able to only criticise etc, latching to the status quo sort of thing, focusing their points on what if this, what if that. This has obfuscated their position in my view and XT sort of gave them amo.
In some ways the real debate has not even started because they have been able to demonise by criticising. The argument... well bring your own options, bring your how, why, when, didn't need to be addressed because all they needed to "win" was to make XT loose and fear/scaremongering is unfortunately often pretty effective if it contains any, however small and out of hand not dismissible, truth.
I've had the opportunity of speaking to some of the more influential small blockers about BU and their arguments so far are from what I can see very ineffective and even comical. They'll be embarrassed to repeat it twice in public.
BU forces them to reveal their true position, that is this settlement thing. We have not addressed the settlement proposal heads on even after some months of debate because the small blockers have tried by all means to avoid it as they know there is no public support for it whatever. They have instead focused on bringing down the alternative, and by definition when there is no alternative the settlement thing wins by default.
There is no criticism they can make towards BU however that in any way has any persuasive power, so they either have to change their position or argue honestly and make the ridiculousness of their position apparent.
Moreover, miners have rejected XT. It is not for me to decide whether rightly or wrong, that's for historians, but they have raised concerns, whether rightly or wrongly, and if we are to think they are self interested parties with a lot to lose and win then we necessarily need to conclude that some of their concerns are valid and need to be addressed.
As we are seeing from the blocksize question, there is a delicate balance between miners and the economic majority. When miners are 100% in agreement as shown by only 3 xt blocks, and the economic majority on the other hand is too 100% in agreement in the opposite direction as shown by all statements, both sides are deeply hurt if they decide to engage in a game of who has the upper hand, therefore both sides are hugely incentivised to come to a solution that benefits both.
The miners are saying that XT may hurt them and their decision says to us that they think it is not in their self interest to adopt XT. We don't want to hurt the miners nor their self interest. The miners have in many ways a bigger incentive than most of us as single individuals, so we need to take account of their concerns.
Even more incentivised however are the businesses (the proxy of us, the users) and the miners do not want to hurt the businesses. Nor do the businesses want to hurt the miners. They are fully dependent on each other. If one is hurt, both are hurt. And there comes BU, offering the perfect solution, calming miner's worries while allowing the businesses to survive, grow and thrive.
Some spanner was thrown into the works however by what can be called ideologues who care not about our imperfect world but about some utopian deluded ideal. They have no self interest and can be considered to be drones. They care not of anything but their delusions and are willing to go to all lengths. Hence the DDoss, the censoring, etc. while at all times social engineering the debate so that their actual aims are not questioned. This, coupled with the isolation of the devs and their escape from light, thus making them highly vulnerable to manipulation, did not provide the opportunity for their premises to be questioned ad initio, rationally debated, and thus dismissed.
Instead a political situation of extremes was created which led to what in a healthy situation should not happen. The economic majority 100% in favour of XT and the miners almost 100% against it. Now that we have unanimous agreement however and the question proposed is whether to raise the blocksize to 2mb, it hopefully will become apparent to all what has been going on because they will be forced to argue their true postion which does not stand light for 2 seconds, but hopefully we all learn our lessons.
The businesses are hurting. The miners do not want to hurt the businesses, hence BTCC and even before that, the miners letter for 8mb. BU bridges all these interests and the BU approach can not persuasively be questioned.
So hopefully we can manage to bring light to the blocksize question, and so show that there was never really any division, but what was manufactured.
