The question posed by the monopolies is not "are these the only options". But do these wield too much market power to be controlled by the market. That is, sure, Bing and DDG make up 5% of the global search, but is that enough. Yes, people use Twitter and TikTok, but does that replace the social graph of FB? Yes, I can buy directly online from many places, but if people are going to Amazon instead of Google to search for prices does it matter?
So, my question to you, if every non-Google search engine published their formula for rankings, and SEO for going up all their rankings was mutually exclusive with going up in Google's rankings, do you believe any site would implement them?
I doubt anyone would trade higher status on every other engine for lower status on Google. And in that case, they may as well be a monopoly.
