Once the company is considered a loss they want to get as much of their money back as quickly as possible. What else would you expect from them?
Is it normal they will literally force you to sell it for pennies on the dollar? I understand that it was their money, how would you handle it? Just sell it and move over to the next thing?
If you can't afford to buy the assets yourself maybe you can find a new investor to buy the assets on your behalf.
Otherwise: yes, you should just move on.
if it's a vc it's not their money (99%) and they have a fiduciary duty to their investors to get as much of their investment back as possible.
that's why...
you could always offer $1,001 of your own money to buy it personally, etc.
