I would think it's just a gui front end for the command.
Sudo dd if=whatever.iso of=/dev/whatever
If it were that simple there would be no need for software like Rufus or Universal USB Installer where it sets up an EFI boot partition on the stick, sets the right partitioning scheme and whatnot.
Also with Rufus you can customize the Windows 10 or 11 iso (remove some of the telemetry, bypass the online requirement, etc.).
Yeah those are good to just make Win10/11 install without a fuss on any hardware and skip the annoying OOBE. There's also MicroWin from Chris Titus' WinUtil that does more than that, but AFAIK it's still WIP and YMMV with how well it does it's job. It can either send you off to a clean, working install, or a botched install, or it'll fail due to missing drivers or w/e.
By the way, I remember there being some FUD about Ventoy having binary blobs, but I didn't check up on that story. Technically it's easy to verify if those binary blobs actually compromise the OS you install from it, but as it usually goes with FUD like this, people act like when something is a closed source compiled binary then it is 100% malicious and there are zero ways to see what this black box does. If that were the case then Sysinternals wouldn't be a thing and Mark Russinovich wouldn't release a book that tells you exactly how Windows works.
Why the fuck is there not one good youtube tui?
Because the terminal was never meant for video viewing and YouTube constantly fucks with any form of third-party access? You can always write a script to download a video via yt-dlp in a format that allows partial playback, and then deletes it after you're done. It would still be janky but it would probably work better than some Electron app. However if you insist on using a YouTube proxy then you're SOL since Neal Mohan has successfully fucked them over to the point where you'll need to pull browser cookies for yt-dlp to be able to download some videos. Just be glad they haven't stooped to going militant against VPN's so you can DL shit through that and use prepaid burners to make accounts for yt-dlp downloading to not give them any data.
Alternatively, consider a different past time if your way of consuming YouTube content ends up being more effort than what you're ultimately getting. Not that I'm saying I'm better than that and that I don't do it, but let's be honest, most of the time we watch time wasting, low brow entertainment trash on YouTube and we'd be better off wasting that time on PySolFC playing Solitaire or Mahjong.
What you gotta realize here is Tim Epicmegagames is and has always been a simp for Microsoft especially after they funded Gears of War as an Xbox 360 and UE3 showpiece that put UE over the top as the second most whored out engine behind Unity. Valve pushes against Microsoft and runs a successful storefront so therefore they are the enemy, hence all the spite moves disguised as necessary for Unreal/EGS like yanking Rocket League from purchase by Steam players or buying out EAC just as Linux support was running.
The funniest part about Timmy is that he flip-flopped on the PC bandwagon depending on how the tide wave was going. When PC's weren't as popular as consoles, he went around declaring that PC as a platform is dead. When PC's ended up being more popular than consoles that became locked down PC's, he suddenly embraced the platform with open arms as if he hasn't renounced his old stomping ground from which he built his empire. He is such a spineless little shitbag it's hilarious, always dancing and prancing around in the way that'll get him the most dosh at any given moment.
