completely agree.
and I know it may seem like I'm heading for the gutter on this ...but hear me out.
If we abandon the tm ..
We still carry on like business as usual...
except for two likelihoods...
we'll be doing damage control from either
A- whatever sketchy business wishes to make a buck off the good name ...where are complaints, where are the people going to go to complain? Here..
B- considering the maemo logo "ae" and name "maemo" the most likely result is we won't be so lucky to have the tm purchased by a hustler...but more likely purchased BY Hustler ..or some triple-x rated service...I can see it now...(really) "Maemo's Motel of Mammoth Mammaries" scoff and laugh all you like ...but there is a very high possibility we will be getting a very odd (and likely unsavory) bunch coming to our door expecting something the majority of us guys just don't have to give.

So say what you wish against keeping the tm ..
I think it wouldn't bode well to let it slip away.
It's ten years of bad luck and damage that can happen ..and then there is the "hope" of maybe reacquiring it. There is no certainty.
And if we got it back in 10 years ..
Then there is the damage control to make our "name" carry the value again..after a decade if damage to it.....more time...

Is all that worth it?
