I am amazed at how easily some of you folks have taken on this "it's their web site, they can do what they want; it's capitalism -- tough crap" attitude. (Whether Google is actually doing that here or not.)
First of all, it's just not good business practice to have an air of superiority that might, even innocently, turn off potential customers. If Google actually wants to take over the world -- even benevolently -- they shouldn't get into the practice of making enemies.
Second, Google is somewhat different in that they have always touted their philosophy of "Don't be evil." Even if you can shrug off this practice, they should not. Is their motto pure BS? Maybe. Folks didn't used to think so, but now they might. Another MicroSquish in the making? Who knows?
