Yes, they are called data brokers and there are a lot of them, e.g. Acxiom, Kochava, Huq, X-Mode, SafeGraph and many more

I’ve been using Authelia for almost 2 years and I really like it. Never had any issues.

Mull is even better, it’s hardened Fennec. It’s basically like LibreWolf but for Android.

Yeah

tar -xvf is the only one I know

And I think it was tar -cvf for creating .tar files?

It’s pretty good for desktop apps, but it doesn’t provide CLI applications, so I still have to rely on the AUR. There are some issues with it, but overall I think it’s the best solution we currently have. And it’s very easy to use, which is great for new users and it will become important if Linux continues growing like this.

It’s more secure than F-Droid. It’s still in a pretty early stage of development though and currently only offers a handful of apps.

• App signing key pinning: first-time app installs are verified so you don’t have to TOFU.
• Signed repository metadata: repository contents are protected against malicious tampering.
• Automatic, unattended, unprivileged updates (Android 12+): updates are handled seamlessly without relying on privileged OS integration.
• First-class support for split APKs: downloaded APKs are optimized for your device to save bandwidth.
• No remote APK signing: developers are in full control of their app signing keys.

I like the direction this is going

Have you tried out Molly? If yes, did you use the normal version or the FOSS build? Btw the Version available on Accrescent is also FOSS

Molly claims to use OSM in their FOSS builds: https://github.com/mollyim/mollyim-android/blob/main/README.md#dependency-comparison. I can’t confirm this because I never use any Signal features that require map integration.

Signal doesn’t “heavily use Google services”. They only use proprietary libraries and integrations for 2 purposes: Donations and push notifications. Signal uses the platform’s native way of handling push notifications, on iOS it’s APNs and on Android it’s FCM. This is also the reason why it’s not available on F-Droid. You can use a fork of the app like Signal-FOSS or Molly. These remove all proprietary dependencies and you can download them from their custom F-Droid repositories.

I’d also put Passbolt on the list, it’s not that well known, but it’s really great. I selfhost it on my home server and I’m very happy with it.

I would recommend you to try out Linux in a virtual machine and play around with it. You can watch this video if you don’t know how to set this up. You can do much more with a VM than with WSL. It allows you to basically try any Linux Distribution, whereas WSL only supports a few distros. In a VM you also get a desktop environment by default, whereas WSL mostly restricts you to the terminal. Sure, you can run graphical apps in WSLg, but you still don’t have a Linux desktop. Lastly, it’s much easier to take a snapshot of a VM, and roll back in case you break something.

After you get comfortable in a VM, maybe try booting a Live USB of some Linux distribution. That way you will be able to try it out on your actual hardware.

After that, you can set up dual boot. That way, you can still keep your Windows installation, but also use Linux without any restrictions or limitations.

Replacing Windows is always an upgrade

Yes

Nextcloud Notes is pretty good. Btw Joplin has an option for End-to-end encryption.

These guys can go fuck themselves

Did you read my previous comment? I spscifically said:

No, because Fedora DOES include proprietary blobs (for a good reason)

You can try GNOME’s Authenticator, it’s pretty simple but it gets the job done
