Nokia (Maemo) - not really, it was more of a side project that worked pretty well for them and still would with such volumes as it got. They had a chance to turn it into something bigger, but waited for too long, playing internal battles between Maemo and Symbian teams, so eventually Microsoft came and pulled out the plug.
OpenMoko - not really, it was major mismanagement in other areas (and some poor luck) that killed it, but AFAIR production volume was actually being predicted quite well.
Firefox OS, Ubuntu Edge - sure.
