Well, your conspiracy is not a prove for me. Put it this way: BTC fails to upgrade for years, need other solution (lets say BCH), now its time for BCH show that its better one and can improve.
This is pretty much the conspiracy behind the Bitcoin Cash fraud. Claiming that Bitcoin failed to upgrade and a "new, real Bitcoin" is needed. Bitcoin has been evolving for a long time, and it keeps evolving. If people need faster transactions right now there are plenty other good cryptos to choose from. There is, for instance, Litecoin, a fork of Bitcoin that does not blatantly misuse the Bitcoin brand in its own name and does not claim to be the real Bitcoin.
Neither you or me here will not prove anything about BTC/BCH/B** and etc. if you were holding BTC than hold every fecking fork coin and trust/believe in whatever you think reasonable. If you are a new buyer, than I would stay away from any of them.
The second some of the Cash folks make claims about the "real Bitcoin" negative trust is the appropriate answer - I completely agree with this stance. This is illegitimate manipulation. It's madness if someone wants to claim a fork of Bitcoin is the real Bitcoin.
