One impression I get from reading these threads is that one-person sites (also blogs) are steadily losing out in google against larger operations. Most likely google's algorithm can usually identify a one-person site from various clues.
As a hypothetical example, why would google send more traffic to a 3-year-old one-person general news site than to the site of a large well-known news organization that's been around for decades?
Of course there can be exceptions. I know of a "news blog" started by one person about 20 years ago that's still doing pretty well. But after its initial success, several new writers and regular contributors were added. So it's no longer a one-person site.
But I think this trend also applies to various other types of sites, both one-person e-commerce sites and informational sites.
