Using the word theory

Please stop misusing the word theory. Here is an excerpt from Ars Technica on what avoid doing: 

Verizon has numerous reasons for wanting its DSL services to die off, including the fact that newer LTE technology is cheaper to deploy in rural areas and easier to keep upgraded. But one of the driving forces is that Verizon is eager to eliminate unions from the equation, given that Verizon Wireless is non-union. None of this is theory; in fact, it has been made very clear by Verizon executives.
