Because design is not about making things pretty, but about making things attractive. Google is not changing their design just because. Behind the childish fonts, colorful interfaces and simple icons there is a careful thought about what Google believes it's the best way to present itself to its costumers. How Google is, or more specifically, how Google wants people to think it is, it's implicitly present in every single design choice, even in a seemingly irrelevant one as the relative distribution of the logo's letters.
