Google only used patents defensively. It is against this kind of abuse, I.e suing the competition instead of innovating. Look at the two biggest players here: Microsoft is struggling to get people to use windows devices and Bing, Apple loves patent litigation and is widely thought of as having fallen behind in terms of innovation and market share.
This consortium is not about protection, it is about attacking Google. Do you think they would even have let Google join? Of they were only interested in protection why sue at all? Google just sits on patents to prevent then being used against them, but these guys immediately start suing. Of Google had won those patients there would be no litigation.
This is the classic definition of patent abuse. None of these guys invented any of this stuff, it was just sold so someone could use it as a shield or a sword as they saw fit.
