Just repeat, “Never ascribe to malice that which can adequately be explained by incompetence.”
They probably didn't figure out that anyone would have a problem with this. For them, it's just a cool gimmick to get some money. That it is a gaping security hole which makes about 0.42 % of user population mad, probably never occurred to them.
Unfortunately, for the 0.42 % (that is us, reading this site, and people of similar interests) it will be hard going to explain to the next 4.2 % why this is so bad. The remaining approximately 96 % of population will stay largely uninterested.
