Firefox and chromium are open source. You can just remove mozilla and google telemetry during compile, or disable in the settings.
no you can't if the entire web runs on a whitelist system that requires the google telemetry, like what google is trying to do with shit like web integrity. you need a sizeable independent browser so that google isn't 70% of the market share like it is now. obvs you can't trust apple to do this because safari is a piece of shit and people only use it because it's the only option, and they'd obviously follow google if it meant more profit. mozilla might do something about it, but their funding is pretty sus.
i understand ladybird isn't good for privacy at the moment, but we're gonna really need it for privacy in the future
