Something to be concerned about or not?

Today, or yesterday according to the clock, I came across an article talking about whose hands control of media outlets falls into. In this case, the article used the statistic that the vast majority of US political contributions made by employees of Google went to the Democratic party to argue that the company is a left-leaning organization.

The article goes on to give an example of a recent removal from YouTube of some material by a right-wing individual, insinuating that political motivations may have lain behind this. (I haven't seen the material in question).

I guess that my question is, if the list of articles displayed on Google News is computer-generated using some unknown algorithm, how much of an impact do you think that the developers' political views have? (Depending on how exactly the algorithm works, this might be one of the better ways of trying to avoid bias in media reporting.)

(There are some statistics that suggest that already the journalistic profession's views may not reflect those of the public at large. Might be true, but then again you know what they say about statistics...)
