>> Google holds absolute authority on how websites are rendered and if websites can be found.
This is still 100% correct. Google owns the dominant browser and the dominant search engine, this means that they get to dictate how websites function and pick winners and losers through their search algorithm. If you're a publisher (i.e. anyone who hosts a website) you're forced to fall in line or go out of business.
