I have seen many people in this community either talking about switching to Brave, or people who are actively using Brave. I would like to remind people that Brave browser (and by extension their search engine) is not privacy-centric whatsoever.
Brave was already ousted as spyware in the past and the company has made many decisions that are questionable at best. For example, Brave made a cryptocurrency which they then added to a rewards program that is built into the browser to encourage you to enable ads that are controlled by Brave.
Edit: Please be aware that the spyware article on Brave (and the rest of the browsers on the site) is outdated and may not reflect the browser as it is today.
Do these decisions seem like ones a company that cares about their users (and by extension their privacy) would make? I'd say the answer is a very clear no.
Edit: To the people commenting saying how Brave has a good out-of-the-box experience compared to other browsers, yes, it does. However, this is not a warning for your average person, this is a warning for people who actively care about their privacy and don't mind configuring their browser to maximize said privacy.
Brave is not spyware. That website you linked is horrible and full of misinformation. They also claim that Firefox, and even Tor Browser, are spyware. They act as if any and all connections a browser makes are automatically bad and used for spying/tracking.
I won't disagree with the other criticisms of Brave that you made, but just wanted to point that out. That website is just highly unreliable and makes verifiably false claims about the browsers it reviews.
What exactly is misinformation? All browsers try to collect data and he mentions it. Brave rewards is complete disaster and spyware. Sure you explicitly need to opt-in, as they are turned off by default.
Using the terms "telemetry" and "spyware" interchangeably makes the former seem more nefarious and the latter less nefarious. I understand where you're coming from but I wouldn't want to see the term "spyware" diluted to include anonymised data about how users are using product features.
That's not to say telemetry data is fine or that a company might claim to only use telemetry data isn't actually using spyware.
