not when you can control 85% of the market and just want your software in front as many people as possible so you can sell them ads. Do you really think google cares that much about making profit on smartphone hardware?
To drive consumer demand in a direction that favors their software and online services, even if its other manufacturers (and, especially, other Android manufacturers) actually selling most of the hardware in the long run.
Not that they'd mind if their hardware took off, its just not the primary goal.
