I think this is happening because a while back, a large company with a TM made a fair offer on Afternic and added that this was their top price and the only other way to go was to meet up in court.
Afternic sent the offer over and the seller thought about accepting it, but countered a bit higher and the buyer subsequently disappeared... only to emerge later with a UDRP that resulted in the domain investor losing the domain. Within the supporting documents was the entire Afternic negotiation, complete with the above statement to the broker.
There was a bit of hoopla about why Afternic did not forward this info on to the seller so he could make a more informed decision about the offer, and it attracted a lot of interest on Twitter X.
Now this scenario is a totally different one, with some nitwit spewing unfounded threats that should NEVER have been forwarded to the buyer, but if this was Microsoft or Google stating legal action was the next step, I'd certainly want to know about it.
