BCH dev. suggests Monero is about as private as using CashFusion on Bitcoin Cash given network-layer attacks

It does not have to be like Monero to give you a similar level of privacy.
It has 2 pools. One anonmous, one open. By such, big coorperations & governments can get AI to crunch numbers, and use the open pool to deanonymise the private pool. This is by no means comparable to XMR. XMR is private by default.
The combinations are close to infinite. It would take enormous resources to get even close to likelihood of identifying correlations.
For the average person it is more than enough privacy. Given the other benefits of BCH it is just the better choice for mass adoption. There will always be a niche use case for Monero but it cannot serve as the world's money, IMO.
