Well.

Naturally there is a long answer that doesn't need to be written here, but naturally there is interest for Nokia so that we don't spend Much Time and Effort in creating something that then some company from Asia could just create a slightly cheaper device, put the same piece of software there (the "100% FOSS Maemo") and make a profit. A hybrid model gives much back to the open source, gives opportunities for developers to do what they want on the platform while also giving some reason for a company to start utilizing open source in their products. Everybody benefits. Even Linus T. understands and supports that. (Recall the GPLv3 discussions.)

But anyway, I'll stop on commenting on this more on this thread - after all, this is about portrait mode support, not about fundamentals of open source.
