Bitcoin entrepreneur Samson Mow says the rise of the BIP-110 movement was driven largely by decisions and behavior inside the Bitcoin Core ecosystem. His remarks followed exchanges on X with analyst Michael Sullivan, Bitcoin Core developer Antoine Poinsot and Blockstream co-founder Adam Back. Mow said the dispute could have been avoided and argued that criticism from his opponents helped trigger the backlash they later faced. He cited the "Zhao/Newberry improprieties" and what he called "a long list of other clumsy, guilty-looking missteps," and rejected claims that his earlier criticism was defamatory. He also said the conflict would have cooled if people had left OP_RETURN alone for a year or two. Mow framed the issue around the difference between a default policy setting and a consensus rule, saying changing the default would have made no practical difference because "everyone knew it was only a default." The broader dispute sits against long-running debate over whether Bitcoin's scarce block space should be reserved mainly for monetary transactions, and it has already contributed to the creation of a new Bitcoin fork that recently failed because adoption was extremely low.
