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.

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.

OS is a personal choice, a messaging platform is not. You have to use the platform that the community is on, but you can choose your own OS.
4get.ch doesn't have the captcha
4get
requires a CAPTCHA per 100 searches
The software itself doesn't require any Captcha, it's just the specific instance you chose that has this requirement. There are many other instances (like e.g. 4get.ch) that don't have a Captcha at all. You can find the entire instance list at https://4get.cynic.moe/instances. It also shows you whether an instance has the captcha enabled or not.
Oh yes, because proprietary software created by greedy, user-hostile, profit-extracting Big Tech corporations can always be trusted. Microsoft would never steal people's data without telling them about it.
