Keep in mind Google is the default browser on Android. Many corporates load Chrome as the default browser as part of their setup process for new machines. For many naive people Chrome is the default browser. It's been a long time since I've seen a a windows machine provisioned by a corporate with Edge as the default browser. Many corporates also warn people away from Edge, Safari, Firefox and other "undesirable" browsers. So IMHO it's not demand from people but really for many the decision has been imposed on them by others.
I don't know why you are downvoted - this is absolutely true. Again, this is not because Chrome ships by default for Mac's or PC's, but because it's a great development target for corp environment and there is a feeling there that security is better on chrome than it was for IE (corps are slow / but have longer memories and IE has had some miserable bugs). Where I work the switch to gsuite and chrome seemed to knock down spam / malware amazingly (if you turn on the delayed delivery / strong malware protection) This does result in I think chrome uploading code or hashes of code you download to google or something as part of advanced monitoring.
