The issue here is that essentially Bitcoin cash is just enabling cheap transactions until their pool of transactions also becomes to large - BUT - its good enough for now, which is a powerful thing in technology and often lets people select their preference so timing is important.
They seem to have drastically downplayed the effect of just increasing the block size
Of course now Kore devs look like fools - they screamed for years that "teh internetz couldn't handle all teh catz", and lo and behold BCH is steaming forward with 8x capacity and speed, without all the
deadweight of Segwit/RBF/L2/LN that still don't exist/won't work/are centralized...
They'll never ever admit they were wrong, but they're already on the wrong side of history. Happy and prosperous 2018 to all here!
