That would be satisfying in some ways, but it's a slippery slope. Who is supposed to have authority over that handle? Who will Twitter/Jack give it to if they do take action? Bitcoin isn't a corporate brand, so it's not a trademark issue. What terms are being broken?

I think people should just get over it. Satoshi didn't care that bitcoin.com was already taken when he started the project. I feel the same way here.
