BTC was hijacked in 2015 by the for profit Blockstream inc, which sabotaged scaling. It has first mover's advantage, but its market share is crashing (about 50% now, from 99%).
All the first mover forums became censored pro-Blockstream propaganda platforms so there were (and still are) huge anti-BCH campaigns being executed against BitcoinCash.
I recommend reading up / asking stuff on reddit.com/r/btc (which provides open discussion with an open mod log). /r/Bitcoin and bitcointalk.org (biggest forums) are both censored.
