Tell us when and why the Unlimited repo commit keys were distributed? You can't, so don't behave as if you are somehow entitled to an answer to your question that is (intentionally) impossible to answer. Pure trolling, because you have no reasonable arguments
Bitcoin Unlimited (BU) operates according to its Articles of Federation. With respect to your question, the GitHub repository is controlled by the BU President (who is presently Andrew Clifford [solex]):
You didn't tell us a definitive "why", Peter. Let me see if I can guess "A democratic Bitcoin, for all!"
Take your democratic business somewhere else, you know there is more than enough opposition (i.e. support for Core) to relegate your Bitcoin fork to an altcoin, and yet you refuse to launch you coin honestly, and instead insist on disrupting this ecosystem.
Fuck off. You're not welcome.
