I guess if we are to believe that it Bitcoin is not strictly a monetary network, then changing the default to allow any type of data is not a big deal.
I am of the opinion that Bitcoin’s purpose is as a monetary network, so changing the default settings to allow for information that is not aligned with that purpose is a move in the wrong direction.
Subversion happens from within. Not saying this is an attack by state actors, but if they wanted to attack bitcoin they would do it this way. Slowly pushing for small changes that are seemingly not a big deal.
