If Chromium becomes incompatible with privacy, the only real and broadly accepted alternative is FireFox. Which implementation, and as always in these kinds of discussions, that depends on your threat model: On desktop, I am very happy with LibreWolf. Mullvad Browser is also great, especially with Mullvad VPN, though it breaks pages a little more often than LibreWolf. On Android, I am quite happy with IronFox.
I often feel a little ‘legislative paralysis’. On the one hand, I want as little government interference in the free web as possible. On the other hand we can see first hand that web anarchy collapses into web oligarchy. I guess the EU is demonstrating that targeted legislation, like one click unsubscribe or one click cookie denial, can improve the web experience and privacy even beyond their borders. Baby steps… When do we get one click delete all my data? And when does a single page start caring whether my browser sends a Do not track request or not? Until then, it’s back to private privacy measures… Even if that’s an uphill battle.
The EU will need to form a proper federal state or be torn apart in the persistent attacks of the other major world powers that actively try to prevent just that unification.
