...or, the non "fake news" explanation:
The present and future market for business telephony is as a cloud-based service, fully integrated with enterprise computing solutions that don't depend on any particular location or device. Employees should be able to use a softphone on their laptop or desktop while sitting at a desk, or on a mobile device while elsewhere. They should be able to use their corporate directory and corporate CRM, calendar and other applications to manage calls, keep track of conversations, conduct online chats and conference calls, and so on, all working seamlessly.
Microsoft's Skype For Business and Google Voice for Enterprise, as well as solutions from Cisco and Avaya, all need hardware partners that can deliver all of the pieces, not just a headset or a desk phone or an app.
Combining Plantronics, Polycom and Obihai, created one company that can competitively bid on all-inclusive telephony solutions for customers who use enterprise telephony solutions: VoIP everywhere, with automated provisioning of phone numbers and deskphones, headsets and conference devices for the office and for mobile workers.
Is it politically-enabled? No; this is a merger of complementary businesses with little overlap. Any political administration, controlled by either party, would have approved this merger.
None of this has anything to do with the consumer market, which is not where the growth potential exists.
