> tautological
It's not tautological to say that you get 100% or 0%. You can't effectively split the population. It almost happened with ethereum, and has never really come close with bitcoin.
It's also not tautological to say "The thing called 'bitcoin' at the time has always been the winner. The thing called 'ethereum' at the time has always been the winner."
> not the correct use of a well-defined technical term
If you want to be really technical, every single update is a fork, and every single time two blocks are mined at the same time it's a fork.
I would rather go with what people were actually calling 'bitcoin' or 'ethereum' the day after any forking of the chain. I don't think it's reasonable to say that we're on a fork of a fork of a fork of a fork of a fork of a fork of bitcoin or ethereum.
> ETC is not a fork and it wasn't 'made' by anyone. It is just the original, unaltered transaction history of Ethereum. ETH was 'made' by introducing a hard-fork and altering parts of Ethereum's transaction history, diverging from prior consensus rules.
All the blocks after the divergence point were made by someone. The original transaction history is part of both.
And I would say that using consensus to change the consensus rules is part of the consensus rules.
