How would that hurt really.
C'mon Hollywood, ( I'm the last one to make apologies for G or to go to bat for them ) that said, if they explain too much, it will be abused on a large scale..and the abuse will be very very bad for both their image, and for their bottom line..
Too many people work out how to keep high spots in organics, the adwords revenue stream will not increase at the speed that Wall street insists upon..
In their position, I think most of us would do the same..anyone not using adwords is a "potential revenue loss" for G ..they cannot make it too easy not to use adwords..FUD and obscurantism* and fear, is about the only way they have to try to keep control of us webmasters as a whole, and they know that it wont work for all of us, the brightest minds are not all in the plex..
Collateral damage has always been part of their algos, one might even say it is necessary to allow the most adaptable to rise, ( fits very much with the Montessori and the Jesuitical way of thinking too ), pre-sorting the SERPS ( in separate cyclical ways with major algos that can cross over and will cross over ( side reference to "mathematical sets" is obligatory here ) but which essentially have different criteria ) in order to keep up the appearance of speed and being the fastest ..
If I were G ..I'd do it that way..knowing that some initial breaking of eggs to make the omelet is unavoidable..
The logic must be..."the smart observant ones will get around it, and live to keep their sites going"..or..if they can't.. they can pay..
Not very "cuddly"..but then if you really look at the Montessori way ..and those who were / are raised in it.. it never was designed to be "cuddly"..nor did it ever pretend to be so..it's products are mostly hyper efficient, and to many would appear to be smilingly ruthless or dispassionate ( below the surface at least )..Bezos is another example.. * my spell checker is bi-lingual ,and sometimes I can't trust it, obscurantism may well not be the way the word for that concept is actually written in English, but my system doesn't give me a red line under it ..so :)
