Calling SEO content high quality is overestimating the nature and level of an SEO article. The other aspect that it implies is businesses are the reason we get so much high quality content. That is provably wrong. The moment people saw that some kinds of links got them high ranking on google, it resulted in an industry of producing SEO garbage where businesses would publish 1000s of words to answer something which could have been answered in a single word. (usual caveats exist)
People want signal and answers, not the 10 blue links as this post tries to argue.
The other thing is this: most high quality and valuable content can now be produced by individuals and finds distribution on social networks where they can occasionally charge for it as well. The drawback to google indexing those links was also that SEO-companies started targeting these mediums (eg: reddit, medium, forums). We needed an early regulation to minimize the needless hacking of SEO, but we let the market play it out, so it should still play out.
