Ventoy is a tool to make a USB with multiple ISOs bootable, letting you select which ISO to use on boot. Another newly-created account claims to be the dev’s friend and translator and has received no contact from the maintainer.
There are some random accounts that do not look like the original creator. I highly discourage from such titles like this post, because we don’t know. “Ventoy” (creator) did not respond as far as I can see.
Edit: Even if it looks legitimate, it can be impersonating to gain trust. Don’t blindly trust random people from new accounts.
It is very much actively maintained other than this supposed vacation from the developer. Everything else is purely speculation and what seems to be impersonation of the dev on the fediverse.
