The domain is not that important than the bitcoin protocol, network and the community.
Everyone would find out the truth not too hard if the .com domain owner did something bad.
If a domain is owned by the person, that support scamcoins like Bitcoin Cash (BCH) then it may be easily used to mislead new and unexperienced users and make them buy a scamcoin that Roger Ver is endorsing. Especially when such people are always screaming that BCH is a real bitcoin. Then a propper domain will make this information see more legitimate.
