Unfortunately, in the substance, BSV is even worse than BCH. They don't claim to be "BTC". They claim that BTC is a scam, there is only one Bitcoin, the one and only Bitcoin is BSV. How far they go turning truth to lies, lies to truth? They present Faketoshi as a reluctant hero, returned to save Bitcoin from the BTC fake-coin scammers. "After a period of denial, Dr. Wright admitted that he is Satoshi Nakamoto" - see below.
What o_e_l_e_o and other are trying to say is that Bitcoin SV is not pretending to be something else, they claim to be representing something.
While not an obvious difference at first it would be like Pepsi starting a new drink and forcing a store to advertise it like
- Coca Cola while the original would be labeled Coke
- Pepsi-Cola and claiming to be the original flavor after the original recipe
Obvious the first one is ten times worse, the second is just a claim the consumer has the choice to believe or disregard but at no point is he mislead by the wrong labeling of the products.
