When the FCC deregulated the phone companies, Verizon took this as an OK 
to put the competition out of business.

They did this to some DSL companies here in the northeast by placing 
fiber shunts in the system and blocking dsl access (dsl does not work 
over fiber) so the dsl companies could not service a fairly large 
segment of the population "sorry but dsl is not available in your area".

They are currently  working on  local telco companies, by providing 
intermittant service to their customers, with a follow up phone call to 
switch to Verizon for better service!

VIOP is a threat to their phone business, which appears to be a cash 
cow, and they certainly will try to protect "Their" investment.
