So here is what we can do: Ohad will take the 500k from the founder share and destroy it, reducing the founder share to 726k and the maximum future supply to 41.5M. From that point, the short term situation becomes exactly the same as if Ohad had decided to sell 500k of his holdings, as he is entitled to, and ended up doing a fat finger while doing so. In addition, the max supply has shrinked by 500k regardless of how many coins are effectively sold, which benefits every long term investor.
Now, you may be asking: won't the fact of taking from Ohad's stash risk reducing his amount of skin in the game and therefore affect his motivation for the project?Well in other circumstances it probably would, but remember that in that particular case the vast majority of the stolen money was picked up by Dor who is Ohad's friend. No good friend would pick your lost wallet and refuse to return it and Dor sure seems like a nice and honest guy, so I'm confident he'll push for Ohad to accept the funds back. Now as we have seen, Ohad is also conflicted by the idea that accepting the funds back would be unfair to Dor. Dor's intervention and willingness to return the funds pretty much saved the day, so Ohad owes him a bunch and will probably want to thank him for that. In the end, it's really something that only Ohad and Dor can solve together, and if I dare say, that's really none of our business.
I think that some sort of cooperation with Dor's project can be interesting and useful and maybe profitable to both communities of coin holders but it have nothing to do with the stolen coin and these have to be taken out of the equation as of now. Whoever got the stolen coins can prove they came from that address and can be compensated by Ohad with btc or new Agora in the pre dump value . I can see a good reasoning behind giving a little bonus for choosing new-Agora over btc since for the project well being it is much better that the btc will stay in the hands of the developers of tau.
