oh, so much fud
atleast try to be accurate if your going to spread fud
bitcoin cash is a bilateral split (true altcoin creation)
the other guys above are listing clients that did not want bilateral splits. even gmax admitted the list refused a bilateral split.
I tried to convince the authors of BIP101 to make their proposal bilateral by requiring the sign bit be set in the version in their blocks (existing nodes require it to be unset). Sadly, the proposals authors were aggressively against this.
The ethereum hardfork was bilateral, probably the only thing they did right--
the list of clients do work on bitcoin mainnet but with functionality/features which core refuse to implement
