I think you underestimate the danger of Google being in this much control. Especially the fact that their browser engine dominates such a large portion of the market. People think they are ditching Google because they switched to a different Chrome skin, but in reality we're well on our way to Google being in sole control of the future of web standards. At the very least Firefox is going to fade into irrelevancy, so we can probably look forward to the slow erosion of privacy and control over the websites we view. Google, the ad giant of the web, specifically developed manifest v3 to prevent effective ad-blocking in chrome and despite continuing v2 support, Firefox is still implementing v3, because of Googles influence. That should have been a wake up call in my opinion.

It's not so simple to appeal to the broader public on their internet browsing habits. Many people have tried, but it's hard to compete with ignorance and multi-billion dollar marketing instruments.
