Most of the type of blogs this article talks about is exactly what I would ignore. Looks more like Google stopped playing the SEO game and is looking for authentic content. Or atleast is cutting down the noise for whatever reason.
And with those kind of websites comment, I meant heavily SEO optimised website. Their content and website are for Google search engine. Not for humans.
Also, I am coming from indieweb POV which isn't about making business out of it. But I do empathise with indie businesses such as yourself. Hope things get better for you.
