One big life-changing thing will be something like Manifest V3, limiting ad-blockers capabilities. https://www.eff.org/deeplinks/2021/12/chrome-users-beware-manifest-v3-deceitful-and-threatening https://www.eff.org/deeplinks/2021/12/googles-manifest-v3-still-hurts-privacy-security-innovation
Rules for thee and not for me kind of stance when it comes to who is collecting all the sweet data from its users, it wont be possible to block every tracker and ad from Google in the future because every add-on will have a limit of how many domains they are trying to block.
I mean what could possibly go wrong if the biggest data collector and ad provider has a monopoly on web browser?
Why is it bad to use chromium base browsers? If the market is essentially only Chromium and Safari, Firefox compatibility will be even less important and broken sites will only lead to a bigger monopoly because users will switch.
