This sort of dismissal based on who you work for is both childish, and unproductive to a real discussion. Similar to the "most fanboyish thing ever" comment, which, honestly, if telling someone their totally unsourced math and claim is wrong, by providing data and real math, is the most fanboyish thing you've ever seen, then i think you are very lucky in what you see ;)
Beyond that, i'll repeat what I said - i simply pointed out the assertion and math is wrong. That is all. You are the one claiming i am defending anything, beyond that, at all. I was very careful about not defending anything, and in fact said i'm open to all sorts of views about what to do about it.
Maybe you should re-read what i wrote, and point out any point where i did anything but show that the claim made was wrong, and the math was wrong?
If it is true, then Google execs should be in jail right now.
And proves point again that Google does not care about filtering content and it is profitable to accept money from criminals.
Ofcourse if your paycheck depends of criminals money then it is very dumb to share that profit to hire more people to fight malware content.
If Google cannot handle their ad business, when there are too many customers, then stop taking new customers.
Very simple.
But taking money from criminals is very profitable and that is the reason.
