With enough Bitcoin Nodes consensus is worthless, meaning they can do a new one. Its wrong because its censorship. Filtering spam out in policy is not censorship. Node runners can decide their own policy, meaning their own Values and Culture. Bitcoin Knots gives you the FREEDOM to set whatever size of OP_RETURN you want and has put sane defaults of 42 Bytes. 100 000 Bytes in Core is insane, and actually malicious. Same with The Constitution. It gives you the freedom to speak out. Your culture and values is the filter that shapes how you use that freedom. Also people can agree on a minimum set of things. Agreeing on larger sets is nearly impossible.
