not sure what exactly that has to do with prebuilt versions of Windows that come with bloatware/adware or other nonstandard customisations?

I think the GP has only encountered business laptops (which don't have as much bloatware). I can confirm that current "normie" laptops (from HP at least) do already have Chrome installed, although it is unclear if this is as part of paid marketing or just to reduce support headaches.

Also, there was the time where Google pays antivirus companies like then-Avast to shove Chrome. Unsure if it is still happens, but this points out to how Chrome can pay through the marketshare.
