You have this story backwards and you should correct your post. Moxie and OWS didn't threaten to sue Wire.
Wire sued Open Whisper Systems. That suit made, but did not substantiate, a claim that OWS asked for money. OWS denies that. I believe OWS, and not Wire.
The genesis of this claim comes from Wire having used GPL'd OWS code, apparently for the Signal protocol, without complying with the GPL. OWS demanded that Wire comply with the GPL.
Apparently, upon being told that they would be required to comply with the GPL, they inquired instead about dual-licensing. That's standard practice when a company adopts GPL code for their own product but doesn't want to comply with the GPL: they instead have to pay for a private license.
Instead of paying for a private license, Wire has apparently chosen to comply with the GPL instead, and withdrawn their complaint. I think that was the right choice.
The knives are definitely out for Signal now that its importance is being recognized by a wider audience. Complaints about Signal are, unsurprisingly, getting dumber and more venomous. For instance, last week, Nadim Kobeissi (the author of Cryptocat, a competing secure messaging system that I think you should avoid) was on Twitter talking about how impossible a GPL violation could have been given that Wire's Signal implementation is in Rust.
