It's a paid product, they are actually allowed to do this. Google is obviously going to focus on security testing with their own browser. It's understandable that organizations want to require chrome for their employees to access their workspace in the interest of security, but it's not the default.

There is zero problem here guys.

If a corporation with my data allowed access to its internal tools using any browser running any arbitrary and possibly compromised third party extensions, that's a data leak and class action lawsuit waiting to happen.
