My opinion - people don't have a RIGHT to a business model. Internet is a free for all, so if someone clicks ad links that is good for for adplatform, if not - sorry, invent something else. You can block me from visiting (in fact it is a common practice of segregation upon IP/regional/adblocker factors) and I can block you from visiting or executing some code on my PC (e.g. ad scripts).

It is similar to people saying that just by owning a car they are entitled for a parking space for it.

Also adplatforms seem to underestimate amount of stuff in the modern Internet and overestimate their own importance - I've switched dozens of tech sites in the last 5-10 years, I don't even remember names of some of them, so even if there will be a mass extinction event for internet media there'll still be lots of stuff to read or watch. Also - ad model obviously does not guarantee quality of material, as we all see on almost all websites.
