The motto? Seriously, the motto? Man, if only Bill Gates had known this he could have avoided the monopoly trials just by creating a stupid motto. He probably didn't bother because he probably never imagined anyone would be naive enough to buy it...
1. PayPal doesn't have a corporate motto of "Don't be evil"
If you think Google wont do bad stuff because of a good PR-stunt, my personal motto is also "Don't be evil" and boy do I have a bridge to sell you.
You may be affiliated with Google trough some of your former projects and don't want to think you are part of something bad, I don't know.
But as an end-user who only sees Google's complete dominance all over the web, as the company who now anonymizes search/keyword-data for site-owners, unless you deploy Google Analytics and further increases Google's grip on the web, etc etc, I see a big beast who could go monster overnight with the rest of the internet powerless to stop it.
Google may not be evil now, but being OK with the power they wield just because they aren't abusing that power is something I cannot be content with. A silly "Don't be evil" motto isn't going to change that.
I'll welcome good options anywhere I can find them, and I don't use Google's products for anything I can't replace with something else. Having another non-Google option in the Android market would be very much welcomed. Especially considering Google Checkout's extremely poor track-record.
Not to mention the fact that even if, against all odds, Larry and Serge truly are completely benevolent they aren't going to live forever. At some point they'll get bored and leave or get old and die. Then the next guy will step into a company that owns most of the web...
Now Google, when are you going to step up to the plate?
