I won't defend or explain Roger Vers actions here. He can speak for himself and he's far from perfect.

"BCash" was a term introduced to confuse users about what Bitcoin Cash is, which has been excused from the start by claiming that it's fair since Bitcoin Cash is "confusing users about what is Bitcoin" and "stealing the name" etc. Participants in the anti-"Bcash" campaign created fake social media accounts, fake subreddits, spammed "Bcash" all over social media etc, just to make sure no one called it anything "Bitcoin" and so that information would be scarce and misinforming.

There had been plenty of non-controversial projects previous to BCH that used the "Bitcoin" name and in fact the full name Bitcoin Cash was chosen specifically for the purpose of not confusing further by simply calling it "Bitcoin" right out of the gates. It remains no secret however, that many Bitcoin Cash users consider it to effectively be Bitcoin.

Personally, I wouldn't mind the name, except there has already been plenty of E-Cash projects previous to Bitcoin Cash that actually used that particular name. Examples would be variances on Bmoney and some payment processor companies that have nothing to do with distributed networks.
