Those reports do NOT show active zero days in signal. The pieces of spyware talked about in those are capable of reading messages once already having compromised a device which isn't insane as if you have access to read storage from a device arbitrarily, of course you can just read the messages. If you want to solve this, A: Use GrapheneOS or an iPhone on lockdown mode with data over USB disabled or B: Use Molly with local encryption.
These systems still only operate once you've opted into them, meaning if you just never enable brave ads or disable it, these systems won't reach you or have any of these possible problems. Personally I don't use these browsers without disabling everything (ads, daily usage ping, ads on new tab page, etc) and once you've done that it is still a pretty great option for a privacy browser especially when considering its better web compatibility compared to Firefox which still lags behind.
**I am not saying Firefox or brave is definitely better than one or the other, I do not want to strike the hornets nest. **
IMO, if you disable all the aforementioned features, it is still good as a privacy focused browser. And especially if you disable things like ads and daily usage ping, you won't be contributing anything to brave devs at all and can use it just as a browser without supporting or enabling the words of their founder.
This is a perfect example of why privacy and security in smartphones is so incredibly important. Delivering food to your neighbors is not illegal and you shouldn't be followed because you put a Mexican person's address into Google Maps or your notes. Absolute insanity.
I hate that we've reached a point in US history where a semi civil war is at risk of happening to stop government overreach from taking and killing whoever they want who gets in the way of their agenda to oppress as many people as possible and reduce everyone's rights to dust.
