Why do you guys think we didn't move to BCH from BTC? Even though the segwitx2 was cancelled, BCH still seems to be Bitcoin 2.0
Because crypto is somewhere in the middle between religion and a Keynesian beauty contest. You don't pick what you like and believe, you pick what you think others will like and believe. As the bitcoin brand name is the de facto property of Core, people think that people think that people prefer the original name "bitcoin", and hence have to follow Core.
BCH is the original Satoshi bitcoin, in the same way that ETC is the original ethereum, sticking to the original principles (in BCH that is on-chain transactions, in ETC it was "the code is the law" which was the fundamental principle of ethereum). But nobody gives a shit about principles. Names and celebrity is what counts, not principles because what counts is selling to a greater fool that has more belief than you.
If you think 2 minutes about it, BTC is stuck in his block size and block time ; BCH is stuck in keeping transaction malleability (solved by Segwit). Both have part of a solution, and both have part of a handicap. When you look at LTC, it has both solutions: faster, segwit (and hence ready for atomic swaps, the true application of segwit), and no religious small blocks. But nevertheless, LTC stays behind. Because greater fool hopes.
