Yeah I find some of their monetisation stuff makes me a bit uncomfortable, such as their cypto stuff integrated into the browser and enabled by default. There was other articles that when browsing to certain site, the browser would inject their affiliate links (https://www.theverge.com/2020/6/8/21283769/brave-browser-affiliate-links-crypto-privacy-ceo-apology)

In some respects I actually prefer Google’s approach to monetisation over Brave, although I don’t install that either. Having a browser billing itself as privacy focused while manipulating traffic to insert affiliate links leaves a bad taste and distrust of the company.

I use Safari by default and Firefox as a fallback nowadays. Very rarely need to run a chromium browser.

According to Steam it’s Left4Dead. That said, Steam only began tracking use in 2009. Not only do I expect my Left4Dead hours to be much higher as I played that mainly at launch in 2008, but I also think that game would be a distant second to Counterstrike Source which I played heavily around release while I was in university.
