https://www.bitcoinunlimited.info/faqBitcoin Unlimited by itself is not a hard fork. It is rather a tool to help the ecosystem to find consensus about a blocksize limit increasing hardfork and execute it. It just enables nodes and miners to agree or disagree with a change. When the majority agrees that it is needed, it can be done. Bitcoin Unlimited is not a contradiction to developer-proposed blocksize limits, to public debates or to flag day activation. Bitcoin Unlimited is not a hardfork to an unlimited blocksize. It is a tool to raise the blocksize limit without splitting the network. An instrument to find and execute consensus.
