I suspect those who didn't were mostly the ones with deeper insight of the underlying technology. When the fork occurred full blocks had already been a problem for well over a year. Segwit was not the solution and overcomplicated the blockchain. This is not debatable anymore. Bitcoin Cash abolished this "overengineering" and simply increased the block size. Disabled RBF making 0-confirmations a thing again. And lastly just recently fixed the DAA. Many think that Bitcoin Cash is closer to the original whitepaper by Satoshi. I'd argue that is true.
Currently the Bitcoin has had 100k+ unconfirmed transactions for weeks... and a ever growing mempool. You cannot transact or move your coins confidently without paying large fees. 500 satoshis/byte or about 30 dollars. The original vision is completely destroyed. Sentences like "store of value" are now the term used to describe Bitcoin. Very far from what the Bitcoin used to be. https://bitcoin.org/en/ is little more but a lie now.
