Journalism has a very short shelf life, and can be costly to produce. Remember, what you read as a consumer is only the end product, there were a lot of calls, interviews, etc -- and those can be costly. You could have a reporter sitting at a city council meeting, for example, for four hours - -and have nothing of value to publish. Or a ton. You don't know.
Beyond that, corporate contributors end up looking more like NPR than open source -- while a company might be based entirely around a DLang codebase, that doesnt really happen with news. So there are underwriters, but it looks more like either donations or advertisements.
