Name, address, GPS localisation data, habits (like apps you often use, moments you use one device or another), gender, search terms in search engines, open web pages on a web browser, connection (other person you know), the work you do and where you work.

All kinds of things, really.

The usage is mostly advertising or identity theft.

Why would you want to be discovered?

Depending on the answer a lot of things can be done IMO.

Try puppy linux ?

Hosting cost money, so an host can setup a patreon to make money to host his peertube instance.

Monetisation like YouTube-monetisation means ads everywhere because, monetisation on YouTube comes from publicity.

Because anyone with a computer can host a peertube instance. Therefore is you want your videos on peertube it will cost you nothing more than what you already have : a computer running and an internet access.

The only real barrier is having the time and the knowledge to set it up.

Peertube is tech solution to host video, not a way to make money with videos. Monetisation can be done with peertube, but it's up to creators to set it up.

Archive.org if you are looking for a public place.

If you are looking for private use, I would recommend taking a small/old PC and run Yunohost with Nextcloud.

Also all depend on the stuff you're talking about...

Libre office draw or Scribus.

Puppy linux (debian version), small, light, 32b.

You should use Ardour, it's a DAW with native linux version. It's free for Linux users and it's a free software.

LMMS isn't really a DAW, as it can't really manipulate audio easily, only midi. Reaper and Bitweeg have native Linux version but aren't free softwares.

Windows Vst are running fine on linux these days, but on Linux there are a lot of audio plugins on Lv2 format you should try as well... Lastly, native vst for Linux do exist and work flawlessly.

Edit: as a general rule, audio in Linux is fairly different than on windows/macos, because it allows more flexible workflows, with the use of multiple softwares in sync to get the best of their abilities. For instance I make professional audio mainly with Ardour but I also use rosegarden, guitarix, luppp, non-daw, open stage control or pure data for some specific functions.

You could try Cyberpunk 2077, Dishonored 1&2, Prey before giving any money to Ubisoft. + Half-Life 2, BioShock trilogy, Fear if you want more action.

If you aren't against rpgs go play Dragon Age:Origins, Mass Effect trilogy or Baldur's Gate 3. Or Alpha Protocol ?

If oldies doesn't scare you : Vampire Bloodlines, Deus Ex, Half-Life, Baldur's Gate 1&2, Planescape Torment, Thief 1&2, and some point'n click games also...
