[VoiceOps] Carriers Keeping Acquired Defunct Company Names

[Peter Beckman]

I'm curious why companies like T-Mobile and Inteliquent/Onvoy/Voyant
continue to retain company names and corporate entities long after their
brands have been retired, acquired, and generally shell entities holding
phone numbers.

Some examples:

     T-Mobile    -> Omnipoint, Aerial Communications, Suncom, Powertel,
                    Sprint, Eliska Wireless Ventures Subsidiary I
     Sprint      -> O1 Communications, US Telepacific
     AT&T        -> New Cingular Wireless, Southwestern Bell, Pacific Bell,
                    Bell South, Southern Bell, Ameritech
     Verizon     -> Cellco Partnership, Bell Atlantic Nynex Mobile
     Inteliquent -> Radiant IQ, Onvoy, Voyant, Broadvox, Layered, Neutral
                    Tandem
     CenturyLink -> United Telephone, Qwest
     Spectrum    -> Charter Fiberlink

So many of these brands are dead and acquired, yet these companies live on
and own phone numbers. Cingular died in 2006. Radiant IQ acquired in 2015.
Bell Atlantic went away in 2000 with Verizon acquiring Bell Atlantic and
GTE.

Why? What benefit does this provide the owning/operating companies? Legal
insulation?

PS -- This all started when I saw Inteliquent request VoIP Numbering for
Radiant IQ in June 2020, a company they acquired in 2015, and generally
does not exist in any meaningful way to customers or consumers, residential
or business. This industry in the US is weird.
