Microsoft is very heavily lobbying organizations to use edge as a standard browser right now. They're doing the same to us. It's really annoying. They're hell-bent on increasing marketshare no matter what.
edit: but honestly, Google could go Apple open source way, making code changes in huge dumps that are impossible to integrate back. But I an not sure it’s worth the trouble.
If they'd actually succeed in capturing the majority of the market, there's a big chance Google would throw in the towel and then what??
Also their consultants are trained to be shills. Every time we have a call with them they will remark about it if we use another browser, even though their area of expertise has nothing to do with it.
