As they say, the winners write the history books (and also the blockchains)

Nope, Ethereum was forked multiple times BEFORE that fork. So Ethereum Classic is not the "original" chain either (if by "original" you mean a chain that can be validated by running software from a time before the first fork).

You are getting downvoted but the internet has a very short memory.

Ethereum's DAO fork and the ETC debacle is why your OG's don't support Ethereum.
