Sad situation, I hope the company is able to reeguer and find a business model that allows product development and support.

I get a question. In the event the company goes bankrupt or owners to leave, as is all the code already "sold"? It would be possible for someone to "adopt" the support without direct connection with the original company?
And it would be feasible to release all hypothesis as open source on github, for example?
I wonder what would be the output, if there were no chances of the company to rebuild.
