Wrong, XT is not "vanilla" Bitcoin, it incorporates significant changes - hence the separate clients and mining software.
Still doesn't make it an altcoin. You have a perfectly serviceable
alternative clients subforum here, yet this altcoin nonsense still persists.
Even as we speak, XT nodes are a paltry fraction of the existing network - 10% with a typical 2% variance on any given day of the week - and has been for months.
Yes, that's why I said: "It's only an altcoin if it forks without consensus. No fork has occurred". It still adheres to the rules of the Bitcoin network and will continue to do so unless more people decide they want those rules to change.
The problem will get solved, it won't be through the "take my ball and go fork" variety of tactics, however.
It also won't be though the "sweeping things you disagree with under the carpet" variety of tactics.
