There’s something not quite right about saying one member of an oligopoly should be forced to follow the dictates of the other members of an oligopoly. I don’t feel like this actually solves anything.
I feel like Mozilla would end up being a Google proxy in this case as they fear losing their funding and Apple and Microsoft would be incentivized to abuse their position to force Google not to do the best thing for the public but the best thing for Apple and Microsoft.
I agree there's already a significant proxy risk with Mozilla (though Mozilla does consider many Google web proposals harmful today), but that is also no less true today, and in fact, today that means Google holds two votes not one.
I would again agree Microsoft and Apple will heavily endorse their own interests, Microsoft much more so in terms of enterprise requirements and Apple much more so in terms of privacy-concerned consumers. The advertising firm influence will be significantly dimished and that is a darn shame.
Yeah, that feels like State-sponsored formalizing of oligopolies into a cartels. We'd like it if they went in the complete opposite direction of less power, not more.
