The problem is that Google owns both sides of the internet - the browser on your computer and the search engine to find everything.
As a result, they control your perception of the internet.
If a site doesn’t work, you as the user thinks the site doesn’t work. You don’t think oh, my browser is broken. Also, if you don’t find a site on Google the. To you, it doesn’t exist.
As a result, you have to bend your website to satisfy both Google search and Google chrome.
That’s why this is an issue. Because of those two things, Google effectively controls the internet, and you as a user or you as a website owner have essentially zero recourse when Google does something that harms you.
