There are no rebuttals because they are too busy attacking a person's character (CSW) instead of focusing on the merits of an argument.
I agree to that.
ABC is the new Core
That's where I don't agree. I disagree with Core on issues such as blocksize. However, most of their team is extremely good from a technical standpoint. Segwit and the features that it will enable (such as Schnorr signatures and MAST) will be extremely useful to the Bitcoin ecosystem.
ABC on the other hand is a bunch of clowns. The team reminds me more of a group of students that want to write a bunch of cool prototype features for a school project. The implementation is terrible and there are no real-world use-cases for the features. I agree that Dr. Wright is a controversial figure, but the technical direction of the SV chain is 100x better than the ABC chaos.
