Several days ago, the indenture trustees for some Windstream bonds filed a motion to invalidate the Uniti lease - see @ZMzV89I
Yesterday (7/3), Windstream filed a preliminary motion objecting to this move. They said they were in negotiations with Uniti and this would muddy the water. They also said this went against the normal bankruptcy process since at this stage in the process, as "debtor-in-possession", it was Windstream's prerogative as to which leases and contracts to reject, not the creditors.

Windstream also says:
"... in the absence of a consensual resolution with Uniti, the Debtors fully intend to assert recharacterization and any other colorable claims and causes of action against Uniti."
In other words, Windstream itself may try to get the lease thrown out but not until they see if they can first get a deal with Uniti.
I wonder if this isn't really part of a tacit good-cop / bad-cop approach by the creditors and Windstream to gang up on Uniti. Uniti knows that Windstream would be cutting its own throat to cancel the lease. But they can't say that about the secured creditors, so the indenture trustees' motion is a more credible threat and more likely to make them cut a deal -- I think. (I'm not a lawyer and this is complicated).
