Some of the points are weak - “scumbag”, for example, is something I hear used by men frequently, and there are reasons why a hacker might go for some data that is not financially valuable, if they have an axe to grind (say, caught his/her spouse using the site).
However, the conclusion seems pretty solid, the above points don’t need to be true for the overall analysis to be correct.
