All feedback in the post is welcome.
Would it be rude to recommend a grammar checker? The topic and supporting arguments for the post are fine (if a little disorganized, but that's common for blog posts). I just found the run-ons a bit distracting.
Otherwise, I agree that the internet is getting shittier. More ads, more walls to defend against scraping, less accessibility, etc. There's no real metric for how well a page presents its contents, only metrics for specific things like load times, layout shift, and so on. I also suspect that, over time, page scoring will shift toward which sites present the data in ways that are more usable by LLMs.
