While everyone else covered the main topic, there is one aspect of her proposal I disagree with; preventing the platform owners from selling/offering said apps on the said platform. (I could be misunderstanding Warren on this, please correct me if I'm wrong on this). Software/hardware integration is a good thing, not a bad thing. Safari and Edge remains the most efficient browsers on their platforms because the platform owners know the deeper levels, they're the most experienced and they're in place to optimize both the software and hardware. Now, one could say that the said platform owners must open up the APIs fully (which I have no problem with as long as it doesn't violate any security / privacy issues), so other browsers could be just as efficient but how would the platform owners know how to improve if they don't try it first? Everything else, I kinda agree with. I would love to see all platforms require a separation/firewall between the platform owners and App Store but mainly because it allows customers the ability to use other tools that is not normally available with sideloading other App Stores and also other OSes (maybe?)
