You won't discuss the other forks because why? You clearly avoid this mere fact that anyone can fork and duplicate Bitcoin, hell they could even fork it, remove the segwit and taproot changes and the 1mb cap and return it to the original protocol as stated in the whitepaper and Bitcoin forums.
There's at least 10 forks so far that I've heard of, all 'bitcoin'.
So what makes BTC Bitcoin when core wants to change the protocol? What version are you on? On this, unchangeable, immutable protocol?
No wonder Satoshi left 😂
