It doesn't matter if Chrome bloats
Google will continue paying software developers all over to bundle a Chrome installer with their stuff, making it almost impossible for an average user (who just clicks OK and doesn't look at the various checkboxes to see what they might want to uncheck) to avoid.
It is worth it for Google because of all the personal data they can collect, the value of which far exceeds the cost of paying to insure that Chrome gets on everyone's PC. Firefox can't afford to do that, and Microsoft already has their browser on everyone's PC. It just comes down to a fight between IE/Edge and Chrome over trying to get/trick the user into making it their default browser.
