Why YSK: good journalism has a lot of costs (and not one-time-only), in time if not in money, so if any “news” source isn’t at least trying to get paid somehow*, then it indicates that the supply at zero price exceeds the demand (it is a “free good”), which means one of two things:

1. a lot of people like and use it but the publisher, or someone backing them, is still paying the substantial costs associated with investigating/researching, editing, and hosting it (and are arguably being quite charitable), or

2. not many people find it useful or access it often, but it is still being offered/promoted by someone who has some other motive (not necessarily nefarious, but also not all that charitable).

If the latter, but they still publish timely coverage of “newsworthy” events, which would otherwise make a lot more people want to read it, then they are likely may be (edited) “tabloid”/“propaganda”/“yellow journalism”/“clickbait”/“listicle”/whatever term people are using today for “not a very credible news source”.

* Even if that’s through asking for charitable donations, though that unfortunately is often not very successful despite the fact that, one might argue, when you benefit and have the financial means to pay but don’t, then that is unethical.

Also, note that the existence of barriers to unfettered use can be considered a kind of “price” (from the “buyer’s” perspective at least), which is both annoying and can serve to limit the “quantity demanded”, making it easier to keep the “quantity supplied” high enough to meet the demand.
