Okay, little Cisco internal secret. They don't even have to buy these statements. They use their size to do it.
They have a service called DigitalSignal (previously Voicestorm).
Basically, they send an alert to their employees to ask them to do various things to promote the company.
For example, I got dozens of alerts asking me to vote for Chuck Robbins for some executive award b---s---. Evidently his fragile vanity needs another external award and they exploit their base for that.
Cisco is one of the most dishonest companies I have ever worked for. Just straight up nonstop b---s--- from day 1. Part of this dishonestly is to game polls and systems using a social media tools.
