I think what interests me the most about this is what exactly is the cause of the liability here, assuming that the product name and company entity wasn't sold off to the current owner. Is it the customer database? Is it the IP / domain of the server? Is it the website that promised it and hosted the contract? Is it the ownership of the app code rights? Because if you think more about it, there is some potential gap here in copyleft licenses which might need to be fixed to protect projects against companies abusing this methodology. Should we tie liabilities to contracts therefore to customer data instead of apps and codes of apps? Is this a glitch in the democratic law that needs to be fixed by the legislatives? In European law liabilities are tied to the legal entities, meaning that there is a transitioning phase of 5 years of the liquidation process until an entity can be sold off by the liquidator, and within that time frame customers must file their complaints/liabilities against the legal entity if e.g. they want their money back. That is unless a judicative / court decides otherwise and puts responsibility onto the owners if there is illegal ownership behavior (e.g. fraud) that was provable.
