I think it has more todo with the fact that the userbase on nostr is a fair bit smaller than on other social platforms and has a more homogeneous crowed. I mean we're pretty much all here because we don't enjoy the other platforms. I also don't think not risking a ban enables friendlier communication. There are a lot of stupid people and stupid people do stupid shit, to put it frank. Time will tell how well the platform handles misuse.
