(2) Accepting BCH for payments is trivial for all the companies and payment processors that previously accepted Bitcoin but stopped due to high fees and unreliable confirmations. BCH is a drop-in replacement where as supporting BTC is more complex due to segwit (+ further complexity should LN be viable).
Of course accepting BCH is trivial for those who already accept bitcoin.
All BCH did is increase the block size while keeping all witness data in mined blocks.
It could be seen as sweeping a problem under the rug, or as kicking the can a few feet further down the road.
BTC is more complex due to segwit - and hopefully soon LN too - because it's evolving in order to survive the technological challenges. It's not sweat-free. No free lunch and stuff. The benefits of upgrading will be more than worth the sweat for merchants (little sweat) and users (no sweat as soon as the first user-grade wallets become available).
But why am I explaining this to you? You are a technical person, aren't you?
