There's not that much that you have to do. Just take the code, put a FOSS license (e.g. AGPLv3 or BSD 3-clause) on it and publish it.
That does actually look interesting and might revolutionize parts of the Fediverse, ngl. Is it open-source?
What shortcuts are different? Basically most of web browser shortcuts are universal, e.g. Ctrl/Cmd + L to focus on the URL bar, F5 or Ctrl + R to reload, Alt + Left/Right arrow to go back/forward, Ctrl + D to bookmark, Ctrl + T to open a new tab, Ctrl + W to close a tab, etc. I've been using these for decades across different browsers, god damn they even work in Apple's Safari
You don't have to use Google services. They are fully optional, and not installed by default. AOSP/GrapheneOS without Google services is very usable, there are only very few things you can't do without proprietary services. You still have the option to create a separate user profile (which are also improved by GrapheneOS btw) to install Google Play services, and keep it isolated from the rest of your apps and data.
How would you pirate macOS? It's free (as in beer)
It's great. It's essentially Firefox, but without the unnecessary bullshit like Sponsored sites or Pocket integration, and it has some quite significant privacy and security improvements. Also comes with uBlock Origin pre-installed.
You don't need to compile it. There's a librewolf-bin package which provides a precompiled binary, or you can use the Flatpak.
Added it to the list.
LibreWolf is much better for privacy, it's specifically optimized for that. It also ships much less bloat by default.
It's not the "AI nightmare", it's a nightmare of capitalism, proprietary software and user-hostile behavior by a greedy, profit-extracting Big Tech corporation.
