Sort of. But not developers in the sense of anyone in the Maemo community. In the MID, UMPC, Netbook world, you see what are termed "reference devices" or "reference designs". They are produced by companies like MOTO who are looking for companies who want to have MOTO develop a device based on the reference design, slap the company's logo on it, and manufacture it. The company would then try to sell it as if it were their own.

Note that if you do have a few million dollars in your back pocket, MOTO would be glad to modify the reference design to address the shortcomings people are pointing out.
