Comparing BCH to BTC is like comparing a real $30k rolex to a fake plastic rolex that cost you $10. To the uneducated they may look the same or even the plastic one slightly better, but to those who know their stuff, they can see one is just a cheap rip off and the other is the real deal.
how can we as community help on that ?
Actually, we can't do anything about it since Bitcoin are created open source under MIT license But we can educate people to choose the real Bitcoin Core. @clrpod analogy could be countered by plagiarism could be punished under the law, but Bitcoin isn't. The only thing we need is to make a newcomer able to testify themselves about the current situation about cryptocurrencies spaces and tell them hows it's started, and who is covering the lie which is the Roger Ver Team.
Agreed, not much you can do except for trying to educate people and push them in the right direction. No legal recourse can be taken unlike in my scenario (though I don't think many people do get punished for selling fake rolex watches, although it's not something I know too much about!).
