I'm not really sure what you are trying to argue here. Your bullet points are equally applicable to "alternative" media outlets and "mainstream" media do often link out to government reports, sources, etc in their articles.
Maybe we're consuming different sets of MSM and alternative sources, but my experience is not only that they are not equally applicable, but that your suggestion that they are is completely ludicrous.
95%+ of MSM articles I read that reference an external document do not link to it. MSM articles are usually littered with links, but they're internal links to lists of other articles by the same MSM outlet about the topic. Meanwhile, the idea of a blogger or YouTuber doing this - just, say, declaring that the government has announced something without providing any corroboration - is basically unimaginable to me; I've never seen it happen as far as I can recall.
Does InfoWars count as "alternative media"? I mean, it's clearly not "mainstream", but the format - the medium - is no different to a mainstream news show. I wouldn't've thought it fell into either of the two categories we're discussing.
