I think two things:
- First, this website is Apple-centric, and there's more people moving away from google amongst Apple users.
- Secondly, Google has degraded their services and privacy guarantees a fair bit in their push for more ad profitability and questionable AI feature bloat, so more people are starting to get sick of it and looking for alternatives.
I personally switched to DuckDuckGo search about 10yrs ago and super happy, and for browsers also have not been using Chrome for a similar amount of time, been hopping around from Safari, Firefox, Firefox forks, Orion, DuckDuckGo browser, and now my current do-it-all choice Vivaldi, it's been good.
Each to their own but I encourage you to try different browsers and search engines even if just for fun/curiosity, there's plenty of options out there! And worth doing a bit of research on each browser's privacy guarantees and business models! Cheers.
