@c3po@mastodon.technology Mozilla's telemetry working is public and has been openly explained many times by the company; that guy Caleb didn't reveal anything revolutionary. However, although Mozilla's decision to configure telemetry as an opt-out is really debatable (it really is), hopefully every privacy concern could be solved deactivating an option within an app. There's no perfect browser in the market: it's just a matter of choosing the best option available, which, IMHO, is Firefox (or any derivative).
