.. and about a thousand less privacy violations. Plus significantly less ties to Google.
Even chromium-based web browsers are tightly coupled to Google. They rely on them for 99.99% of their source code. Mozilla just uses Google as the default search engine.
If I had to estimate, the developer time required for Mozilla to change the default search engine is ~.5 hours. In order for, say, Brave to not be dependent on Google, they'd have to spend ~100,000 dev hours. Because, you know, they'd have to completely develop a new web browser.
