I don't get it. It will actually be bad for BOTH chains if indeed Bitcoin forks into two. Some people who are following the space could see this as a weakness and another reason not to start investing or accepting BTC as payments. Imagine if you were a merchant and you have to go thru and be involved in this sh*t, with all the debates and the drama. And worst of all the uncertainty of BTC's future.
It has always been and always will be possible for a split. It's good to test this. Once tested, we'll lose the uncertainty if it ever happens in the future.
After the fork, any business transacting will get to choose between using $1/tx core coin or $0.01/tx unlimited coin. Hmmm, tough decision.
The real risk that Core seems not to care about is of people moving to an alt that allows cheap transactions already.
A functioning well tested Lightning Network built on 1 MB Core coin and implemented across all wallets I believe would also take Bitcoin to the moon, but it DOES NOT EXIST, and won't for some time.
