That linked reply doesn’t explain anything. It just says “bro trust him”. Just because you and the AUR maintainer says its trustful, does not make it clear whats behind the binary blobs. It doesn’t matter what anyone says, if we can’t verify. In my opinion, its absurd calling others absurd for not trusting the word of others.

I used Ventoy (its still on my USB stick). Its actually a pretty cool concept. Normally without Ventoy, you would flash your Linux distribution on the USB stick. And then you can boot from it, right?

Ventoy instead allows you to have a folder where you put an ISO without flashing it, and then you can boot from it by selecting in the menu. You just need to flash Ventoy once, as the base system, then you can put as many ISO files into that directory. I tested it and have 7 different Linux distributions (ranging from 1 GB to 4 GB variants) on the same USB stick, and I can boot any of them without flashing again. Replacing ISO is extremely easy, just delete it and copy a new one. Filenames does not matter, anything can be found.
