Language is constantly evolving. 'Gay' and 'fag' are two striking examples of two words that are generally used in completely different ways.
There are countless other examples, but you knew that. You can argue that there is some downside to this, but that's about as far as you can take it.
At the same time I don't see any downside with the use of 'corporatist', and it has an intuitive feel to it with the use you're objecting to. If you really wanted to nitpick Cenk's choice of words, go after his relaxed use of the word 'theory'.
He makes the (incredibly) common mistake of saying theory when he should be saying hypothesis, or something along those lines. The only reason I care is because it helps feed the idiotic idea that 'evolution is just a theory'. Yes, it IS a theory, but the "just" qualifier is due to confusing theory with hypothesis.
See my example of how it influences the evolution/creationism nonsense. People say "evolution is just a theory" when what they're really saying is that it's "just a hypothesis" which is incorrect.
So even though I understand your point, when you say "hey, let me run this theory by you" you're (unintentionally) undermining the credibility and meaning of "theory" which comes back to bite us.
