I do disagree with that.
Making a wide-ranging edit without bothering to understand community norms is vandalism. If I paint the 12th century church down the road purple without asking anyone, that’s vandalism whether or not I think it genuinely looks better purple.
As an OSM example, in the UK we occasionally encounter muppets who decide they know better than the settled will of the community on highway tagging. They therefore take it on themselves to extensively retag a bunch of roads, and generally get a hundred or so in before anyone notices. Wikipedia calls vandalism “damage to public or private property”; blatantly overwriting the will of a community with your own opinions fits that pretty neatly.
