Seems like adoption as a payment method halted when Bitcoin had scaling issues.
Now the community seems pretty split in two. There's people who are for Bitcoin and see it as a store of value and people who are for Bitcoin Cash who see it as a store of value and a method of payment.
The main contention seems to be around block sizes and wether to increase the block size to make it more scalable, hence the BCH fork.
They both want to scale transactions, they just disagree about how. Bitcoin Cash wants much higher transaction throughput at the base layer (i.e. the actual blockchain). While Bitcoin wants the high throughput lower value transactions to happen at layers built on top of the base chain, e.g. Lightning
