Not only that, if Chrome gets enough marketshare on iOS Google could do things like taking away 5-20% of a huge fraction of iOS devices' battery life just by shipping a somewhat less efficient build, plus doing the same with any embedded versions they'd manage to convince everyone to use in their apps. I mean, Chrome's already less efficient than Safari, so that much of a penalty might happen regardless, but they could accidentally-on-purpose fail to optimize new features in their iOS code to harm their only competitor in the mobile OS arena. "But developers and users wouldn't stand for that!" OK except I can take 4-6 hours off my M1 Macbook's battery life by using a couple Electron apps and favoring Chrome over Safari. Lots of people do exactly that, maybe not because they want to, but because they need those crappy programs to get work done.
