Because they're two different things and Maemo 5 is not equivalent to the N900 (in fact, it's been run on the Beagle Board), that doesn't mean other manufacturers get to ship Nokia's proprietary software and abuse their trademarks, however. Software aside, Nokia doesn't license the brand, so other companies can't just start using their trademarks whenever they feel like it. The whole reason Nokia ships differentiation software in Maemo is so that Chinese manufacturers can't just copy it all, ship it on inferior hardware and sell it as Maemo. If the whole thing were open source then there wouldn't be any appreciable difference between what this company is shipping and what Nokia's shipping software-wise. Pfft, because Nokia has firmware locks you need to bypass and 90% of its platform is closed source. Please. Just because Nokia has a reasonable expectation of not doing another company's work for them doesn't turn them into an evil company.
