If the goal is to build a browser, then everything else (the alternative ecosystem, the alternative OS, the alternative hardware, the custom chips for the hardware, etc.) not required for the actual browser is waste. That's the exact opposite of efficiency.

The issue isn't chrome's ecosystem. The issue is that Chrome is being used to create unfair barriers of entry for Chrome competitors which then allows Google to use Chrome to harm consumers because there are limited competitors for consumers to switch to.

Secondly, the issue isn't that google added DRM to chrome, it's that the DRM was pushed into an ostensibly open standard, but the implementation of that open standard is locked behind a licensing agreement with Google because it's illegal to make a compatible client under the DMCA, since that would be considered copyright circumvention.

If instead google and HBO had made a specialized browser app to handle the DRM or even just a browser extension that enabled the browser to understand a nonstandard html tag, then the argument that Google is using Chrome's footprint to to modify open standards to make it harder for people to compete with them starts to fall flat on its face (cw. no one is complaining that an HBO app for android and iOS is a monopoly that needs to be broken up). But doing it that way makes it much harder for HBO to acquire customers, because it requires customers to install a new app on their PC or an extension in their browser.

At what vision?
