Consider it primarily as a vote of no confidence in the Bitcoin Unlimited software and development team as it currently stands. I'll add the contingency that the deal is null and void if there are major changes to either.
I get it.
Funny thing is, as a BU supporter, I put more weight on your announcement than anything anyone else has said or done,
as far as shifting my opinion.
I still think we'd be better off with BU than Core, but at least you made me take a step back and try
to see more.
I am wondering if you see any problems with Core's roadmap (some people have gone as far as
to say they are deliberately trying to bring down Bitcoin)...or you agree with small blockism in general
(centralizing transactions over centralizing nodes or Bitcoin-as-commodity-not-currency)...or simply
you weigh those factors less than network reliability.
