This has been suggested many times in many variations and Dan is very much against it. His perspective is that it's Adam's property and so it should be only his decision what to do with it. IMO the problem is that it was part of a decision he didn't want shareholders voting on (merger and allocations etc).
What's done is done, maybe it was unjust but it will come back to bite BTS when people don't want to use the BTS main chain for stuff.
Well in my view it does not mean that we (the community) and Dan cannot express our strong opinion that it is best if Adam voluntarily burns said funds...if he choses of course, but you know... we strongly encourage such a move...
In other words it is indeed Adams property! I just want him to come and openly say "It is my property, I deserve it for what I have (not) done and so I will keep it!"
[edit] And no, I have absolutely have no clue if BTS is marketable in its current state, but marketable or not I was not the one promising marketing results...and then saying "Thanks for the half a mil, but do you know what I will do nothing".
