Yes but how reliable are the other sources? Anyone can easily set up a website and put some articles.
The distrust of "mainstream media" is a paradox. You can't trust a brand new website for reliable information, because it could just be a random person making shit up. But once a site has been around for a while and has built up a reputation, it gets labelled as "mainstream media" and therefore also shouldn't be trusted.
Besides that, a news site has to be fairly large to be able to afford having journalists spending time investigating stories. But opinions are cheap, and that's generally what the indie "news" sites are. Mostly just a collection of opinion columns with little to no stories resulting from investigative journalism. Sure mainstream media is doing a lot of opinion too, because its cheap and makes money, but at least there's going to be some people at a larger organization doing actual journalism.
