They figured out ways to get data to kind of be tacked on to some transactions, I am not a dev or computer scientist so can’t explain in great detail but I donno kind of same argument as government “don’t damage or alter the notes” well these people are claiming to have sats with graffiti on it I guess and they feel that makes them more special and valuable, good for them. Others care only about fungibility and want to maximize that. Market dynamics and forces at play. I like watching and fiddling anyway not too concerned about trying to bend much of it to my will or what I think it should be.
