Discord: Their are custom clients like Vesktop that fix streaming on Linux and add features

Da Vinci: You can use this project for easier use, or just get Kdenlive which is fully supported on Linux

WhatsApp: If you do want to call people you could use Waydroid and install the android version, or if you don’t need calls but want background notifications you can use Zapzap

There is Neonmodem as a TUI client

Printing has basically everywhere been annoying. You need(-ed) specific drivers or even apps to make it work and if you have that set up it still can be annoying. And because most of these drivers/apps don’t support Linux printing relied on reverse engineered drivers. Then CUPS came around which made things better. And when apple adopted CUPS for Mac suddenly everyone wanted to support.

If you are really interested check out this episode of destination Linux where it’s discussed in detail.

I believe you can just do youruser: and chmod automatically uses the correct group. The other user is also technically correct as the usergroup is called the same as the user so both commands are the same.

Use chown to change ownership or chmod to change rights. The -R option makes them also change the permissions for all files and directories inside of the directory.

sudo chown -R <username>:<usergroup>  /pathto/Files

Discord would be the obvious answer, but I understand why you might want to use it, my recommendation is using a client that disables some of the tracking like Vesktop. Spotify is also a major privacy concern, it can be replaced by Spotube (and to a lesser degree by Audiotube) which removes most tracking and is three and convenient. Also I’m not sure if I would keep using chromium, especially with manifest V3

I think the main reason is that most people who use Linux installed it on their own and at that point no parental control is stopping you.

What about Epiphany/Falcon? They are AFAIK built from scratch, apart from the engine. Would you still consider them clones?

Parental controls are one of the under developed parts of Linux, the only major one I know of is timekpr

For Wine: Microsoft 365 and anything Adobe notoriously doesn’t work with wine, any solution will most likely not be permanent.

For Premiere: Kdenlive is the best open source alternative IMO and there also DaVinci Resolve which has a free and a pro version. It is also more professional. Be aware DaVinci has problems with GNOME, which is the default environment of Ubuntu.

For distro: Nowadays Linux Mint is the best for user friendliness. If you will be going for a tilling window manager, the typical easy distros won’t make that much of a difference as you will be replacing a large part of it. You could probably do everything with KDE though with window rules and this, if you are going to use KDE then maybe use Kubuntu, it is a official version of Ubuntu with KDE. Ubuntu flavors

LMDE uses Debian repos which are very well tested, meaning stuff like the XZ back door will most likely not affect you because it is found before you get the update. ClamAV is not designed to recognize malware for Linux only on Linux, so not what you want in your case. My recommendation is to stick to distro packages (well tested) or flathub (sandboxed), which are available in mints app manager. If that isn’t an option try getting the software as an appimage, it isn’t sandboxed but also doesn’t have root access. Otherwise general rules apply: be wary of sketchy websites, use ublock with the malware filter list etc.
