If it weren't them, would it not be somebody else? There was a time when Internet Explorer was the browser to code for, the one a person might reasonably choose so everywhere they went online web pages would work as intended. You could use alternative browsers, but sometimes things just didn't work.It's just a reality of how badly Google has warped the browser landscape.
On the other hand, even with Chrome, we can use alternative browsers. Using a Mac, I went with Safari by default, but Chrome to a lesser extent.
How do you think the browser landscape would look different without Google? Would we be having this conversation about Microsoft and Edge instead of Google and Chrome?
