``Why should a company have to release a statement about a takeover anyway?,,
On of the reasons would be to validate edits in information-related services such as wikipedia. That iMesh is claimed to have purchased the "Lphant P2P network" is not related. This article is about the client. (Besides from the fact there is no Lphant P2P network.) Finally, if iMesh/Discordia/Merlin whomever hold the rights to the application, they will soon request from major download sites for it to be replaced with their own client. That will set the matter in wikipedia as well. Until that happens, acquisition of a domain name does not have any impact on this article.

As for Bearshare, I point you to a source from its Wikipedia article:

"It’s possible the May 3rd filing was a means to force Free Peers, Inc. into negotiations and a settlement. As part of the settlement reached on May 4th, FreePeers, Inc. will give up all intellectual property rights to the BearShare name. This includes the BearShare source code, all associated domains (over 100), and its massive user base."
