I would like to bring your attention to Google’s recent proposal to add a feature to its Chrome (Chromium family) of browsers called Web Environment Integrity. This provides a mechanism to reinforce Google’s already dominant browser market position by creating a technological control that can be used to nullify a user’s choice of browser, device and operating system. This technology also has the potential for abuse by preventing users from using browser extensions that can enhance security by blocking unwanted and potentially malicious content, as well as browser extensions that help vulnerable users with enhanced accessibility needs, such as color blindness and visual impairment.

Google’s dominant, near-monopoly position in the browser market already harms me as a consumer by reducing browser choices and preventing a competitive market for developing new browsers. Allowing Google to include this feature will reduce my browser choices and consolidate the browser market even further, and it is incumbent on [INSERT AUTHORITY HERE] to take action against this abusive behavior.
