Instead of government leaving it up to "market share", in an industry with decades of documented history of underhanded anti-competitive behavior, how about: 1. All government Web frontends must be compliant with one of the government-defined profiles of browser features, which are defined in terms of W3C (not WHAT, not Chrome) open standards. With sufficient penalties to motivate compliance. 2. As a practical matter, developers of government Web-based systems -- in addition to developing to documented open standards, and using open standards-based libraries/frameworks -- will be motivated to test with multiple browsers, including Firefox, because that's the most likely way that end users will discover and report noncompliance with the standards and profiles. 3. Government "apps" for non-Web platforms, such as Apple iOS and Google Android, are strongly discouraged. Furthermore, such non-Web apps by default are not compliant unless complete comparable functionality is available via compliant government Web frontends/apps. (To get permission for exceptions in extraordinary circumstances, there will be an onerous and uncertain process, and thus the motivation is to invest in the open standard Web platform for any "extraordinary" platform facilities that might be needed.) (Also there would be regulations about backend implementations; that's just about browsers.)
