Trends matter too. If it gets to be an order of magnitude cheaper to shill your products on social media and forums, set up seo crap articles to phish users from search results, or churn out good old fashioned email scams, then expect an order of magnitude worse signal to noise ratio on the internet as a result. There could be a point reached where the internet is functionally broken, with the signal to noise ratio too low to make it useful for anything, save for navigating directly to known good hosts that themselves will become increasingly more lucrative targets for enshittification.
