BusyBox developers go after Verizon

The Actiontec routers Verizon provides with their DSL service are certainly modified by
Verizon, or at least modified by Actiontec to Verizon's requirements.  In addition to branding
the web interface, some configuration options are removed.

I don't know if the situation is the same for the FiOS routers, but I would assume it is.
