It's not clear where exactly Google intends Fuchsia to run, but wide hardware support would be best for a relatively open ecosystem like PC hardware. A non-general-purpose OS, or at least one designed to run on specific hardware, doesn't have the same requirement for a large body of drivers to be available. Imagine if they want it as an OS for a range of embedded devices, or something. Hardware support could be very limited. Especially at a smaller scale like that, Google's got the money and expertise to license hardware IP from another company and build their own drivers for it.
