The only really valid criticism I see here is the binary blob problem-- clearly this is a poor way to store user configuration data, and completely antithetical to the kinds of philosophies that undergird Linux and Ubuntu.
But really, the core of the issue that's been raised by Unity is that Ubuntu seems to be moving away from catering to power users to cutting features essential to them in favor of appealing to more amateur users. One can lament that decision, and even disagree with it, but I don't know how fair I think it is to criticize Unity for lacking those kind of power user features.
After all, it isn't like power users are exactly wanting when it comes to replacement options in the Linux space.
