i dont know what bitcoin maximalism is. i think its supposed to insinuate a group or a person using force to make someone adopt Bitcoin without using force. So you are supposed to not like this group or person because he is forcing you to adopt bitcoin without forcing you to adopt bitcoin. its just nonesense.
But there are probably people who feel coerced into adopting bitcoin without actually being coerced into adopting it. i dont know what to do about that
