I expect this will affect the political impartiality of Buzzfeed journalists. They will have a direct financial interest in discrediting the idea of a free market in the public eye.
If you claim they don't, then you can't draw that conclusion for unionized journalists either
But it's pretty hard for owners to prevent this kind of outcome. You are legally restricted from exercising your right to free association and only employing people who oppose unions, if you ever become an owner.
