The law says they don't need permission to do something like that, regardless of any morality or decency issues that causes. The law is often not aligned with morality.
Most people seem to not really get this, even when they objectively know it, or are otherwise unable to imagine what could go wrong, because doing so basically requires you to be the unhealthy kind of imaginative and paranoid. "What if facebook doxxes me and changes my display name" SEEMS like it should be an insane paranoia, because the human brain isn't equipped to handle extremes of scale and bureaucracy like this.
