Not all porn is equally legal (sodomy, for example). And our society (at least in the US) likes to pretend that it doesn't exist, which means that it's viable ammunition to attack a person's character with, publicly or privately.

So, in practice, this means that these big companies have ammunition which could be used to destroy careers and relationships. Whether used directly or incidentally via a data leak (it's not like those ever happen /s).
