Yes, that is the result of us pre-installing the chrome-gnome-shell extension, which enables you to install extensions via https://extensions.gnome.org - Without it, you'd have to jump through hoops to enable the functionality.
You can validate this by going to chrome://policy. You will notice the policy name is "ExtensionInstallForcelist" and the Policy value is gphhapmejobijbbhgpjhcjognlahblep;https://clients2.google.com/service/update2/crx
gphhapmejobijbbhgpjhcjognlahblep is the extension ID for the Chrome GNOME Shell extension, which you can see via chrome://extensions
To be absolutely clear, we have no access to your data, we do not manage your account. Chromium-based browsers just do not differentiate between installs which have accounts that are actually part of a GSuite organization v.s. an extension simply being pre-installed. You can audit the code here, it's developed by GNOME.
