Bitcoin's BIP-110 proposal has been publicly opposed by several OGs.

On February 24th, PANews reported that Bitcoin Improvement Proposal BIP-110 has sparked heated debate within the community, with several early Bitcoin participants publicly opposing it. Proposed by developer Dathon Ohm, and supported by the Bitcoin Knots camp and Luke Dashjr, the proposal aims to reduce the block space occupied by "spam" by restricting non-monetary arbitrary data (such as Ordinals and Inscriptions) in transactions through a one-year soft fork. F2Pool co-founder Wang Chun, Casa co-founder Jameson Lopp, and Blockstream CEO Adam Back, among others, criticized the proposal for weakening the neutrality of the Bitcoin protocol, potentially compromising immutability, and posing a risk of chain splitting. They argued that the practice of reviewing data types at the consensus layer is inherently more harmful than the so-called "spam."
