Here's a graph of the value of Windstream's unsecured bonds – they're currently in default and paying no interest:

Click on the tabs that say "1w", "3m" etc to see price graphs for the last week, the last 3 months, etc.
The value is expressed in cents on the dollar vs. the face value (100).
The owners of these particular bonds are in the same boat as all the other unsecured creditors such as vendors. (There are other bonds that are secured by Windstream assets but they are in a different, better boat).
Eventually the unsecured creditors are going to get some mix of stock, cash (probably not) and new bonds.
You can use the price of these unsecured bonds as an approximation of the value the financial markets expect this package will be worth. The value today was about 15 cents. A bondholder who thinks he'll get back more than 15 cents will hold on to his bonds. Someone who's more pessimistic will try to unload them.
You can see where the bonds plunged from about 70¢ to about 15¢ when Windstream filed bankruptcy, then they recovered to almost 30¢. If you look at the 3-month chart, you'll see they've steadily drifted back down to about 15¢.
In other words, unsecured creditors have become more pessimistic since mid-summer.
Uniti's stock has sunk some, too, over the last 3 months, but not as badly and it's recovered a little bit recently:
