Google's Software Principles

Nick writes "Google has just posted a new set of "Software Principles" at their site on how they feel about spyware and the like. It is interesting to see the company whose motto is "Do no evil" trying to get the rest of the internet world to follow, with proposed principles dealing with upfront installation, clear behavior, simple removal, and keeping good company. The question is, though - why would a company who makes spyware (whose very nature is to be secretive and hard to remove) want to follow Google's principles?"
