On one side of the OP_RETURN debate, you have Ethereum sympathizers, butthurt Counterparty alums, devs who can't fix simple bugs, devs who accidentally programmed inflation bugs into Bitcoin, and people who want tail emissions on Bitcoin. On the other side, you have a dev who saved Bitcoin from an existential bug in 2013, finally figured out a way to decentralize mining after years of stratumv2 vaporware, figured out a way to get lighting while simultaneously fixing the malleability bug (which other devs though was not possible), and Bitcoiners who want sovereign money. Tough choice
