That's not entirely true, as this is community logo, Nokia never had this, from your first link:
Here is the new logo of the Maemo community. Please be sure to use the logo in context of the Maemo community and not in context of Maemo, the software platform that powers Nokia devices such as the Nokia N810.

Unless maemo community trademarked its logo and not got this as a leftover from Nokia. (but community logo is under copyright anyway, someone created the design, so you don't need to go and register for 2k euro just to use, same as if you created a comic, you're covered).

btw tradermark policy doc references (www.maemo.org/intro/trademarks/logos ) which 404s

It looks like we already are overdue in US (someone mentioned it lapsed there), poo-tsunami did not happen. What exactly will happen, sorry to call it fear-mongering, but will... I don't know, Xiaomi register that TM and release Maemo-android phone? (that actually does sound scary/nasty) This website is safe (been in use for far longer than whoever will register TM). And it's not like in the southpark episode that people ran out of company names, so if they release a product called maemo (I don't know, inflatable duck for example), don't see how that hurts Maemo as a platform
