In this article's context (Windows), you would have put in the effort to download Chrome yourself and then used it, which is a heck of a lot of intent, as compared to what Microsoft is doing here.
That still wouldn't justify being asked a hundred times. But I also cannot relate. I use Firefox as my main browser and start Chrome and Edge semi-regularly. Only Edge keeps asking me to make it my default browser. And then of course there were the few times where a Windows update "accidentally" set Edge as my default browser.
The second checkbox in Firefox's Settings panel is "Always check if Firefox is your default browser" and I have every reason to believe that Firefox respects that setting. Do the other browsers not have a similar setting? I don't have Chrome so cannot check but Edge doesn't seem to have this at the top of their settings and perhaps nowhere in their settings. Consider a browser that's not so hostile :D
I use Firefox as my default browser and only open the other two occasionally. Just last night I opened Chrome and Edge, and once again gave me a big dialog about applying suggested settings. The only setting was to set it as my default browser. And the options were "ok" and "later".
