The PayPal and Google lawsuit is just another one of Google's seemingly endless big-name legal tangles over the last couple of years. Why is Google litigation such a frequent topic?
At least in part, it's because Google has one of the most aggressive stances towards litigation of any member of the tech industry. Google's reputation for taking its battles to court has become almost notorious (well, except for the "Buzz" incident) - regardless of cost or, sometimes, likelihood of victory. Google's approach is one of the modern corporation - during the 1990's and 80's, when civil litigation was actually more prevalent, in-house counsels for major corporations often preferred to settle potentially high-dollar suits rather than risk wasting piles of cash on defending them, only to lose in the end.
