Again. Nonsense. The first link is incredibly old news that Brave has both rectified and apologized for, but seems to be something that anti-Brave folks want to hold onto for the rest of eternity and it’s actually a big nothing burger at this point. This is basically the only bad thing they have done and when you compare it to the atrocities of Google and Microsoft, it's infinitesimally irrelevant by comparison. The second link is even older and requires the consent of the user to opt into receiving alternative ads, and the user can also get paid for the ads in crypto. The option is mostly off by default, but you can completely turn it off in the settings and never have to think about it again.
We all know what Chromium is and it's not "nothing more than Chromium." It's been stripped of all the data-harvesting Google garbage and replaced with crypto-centric alternative advertising that the user has to willingly opt into in order to see and again ... can be completely turned off. If all the ad blocking features are turned on, I generally get a 99% ad blocking result with online ad blocking tests. If you want even more ad blocking, you can add your own custom filter lists like you can do with uBlock Origin. There's also anti-social media features built in as well. The iOS version of the app has the best ad blocking of all the browsers available on iOS. Brave even has a background audio feature that lets you listen to things like YouTube in the background without having to pay for YouTube Premium.
There aren't any better alternatives at this point. You can use Firefox, which only exists because Google allows them to exist. Almost 100% of their funding comes directly from Google as they don't want to appear to be a monopoly. So if you think using Firefox is fighting the good fight, it's an illusion. If you use a fork of Firefox, like a "hardened" Firefox, then you generally miss out on things like syncing across devices. Brave can be thought of has "hardened" Chromium.
Safari is okay, but there's no privacy-based search engines you can use as it's been made pretty clear that DuckDuckGo gives their data to Microsoft and even now there's still no option to add a custom search engine. The fingerprint blocking also leaves a lot to be desired in Safari compared to other browsers, especially Brave. Brave has Brave Search, which is still a work in progress but is getting better all the time. Brave is also the only browser that blocks Google trackers in the Chrome Web Store.
There is no perfect browser. And none of the browser companies have a perfect track record. Brave has made mistakes, but they've rectified those mistakes and the issue has been seriously way overblown. Let it go already.
