My biggest gripe with them is the subject of this thread:
(their "toolbar" defaces web sites, illegally infringes on my copyright and adds outgoing links to my web pages and thousands of web masters are having to add code to every page of their web sites to stop this theft).
Yes, I also have big issues with their policies re the sandbox. The sandbox is a compulsory penalisation of web sites for competitive search phrases of anything up to and above a year. Basically, if you have a new web site - no matter how good it is and useful it would be to the public, it is buried thousands deep in the results for an undisclosed period of time. Of course, during this time, you have little choice but to pay for listings - and it'll probably be with google adwords.
This practice does nothing for the search engine users and denies them some very useful information just so that google can get revenue from the PPC (Pay-per-click) model.
I have issues as to why they need to place a cookie that uniquely identifies me and that will stay on my machine until 2038!
I have issues with them providing the browsing history of their users to the US government and the fact that they refuse to explain why.
I have issues that they are just about the only people that have software (the dreaded google toolbar) that updates itself and installs new programs on your computer without even asking you first!
Other than that, yeah, happy birthday
