While allowing the end user to select their "start" GUI, Microsoft may have felt that if they give the end user the choice, few people would actually use it, which would defeat the purpose of having a new interface.
Yes! This is exactly the point!
The same thing happened with the ribbon bar in MS Office. Given the choice, most users would not use it. Why? Because, for experienced users, it actually reduces their productivity. The ribbon bar is still having a negative impact on my productivity in programs like Excel.
This is a marketing decision, not a usability decision. The interface formerly known as Metro is a one-size-fits-none solution imposed by a company that is once again releasing a "Me Too" product that is too little and too late. The only way that they can ensure adoption is to impose adoption on hapless desktop users.
