I remember a story where people asked about blobs included in Ventoy and there were no comments from the devs, leading to suspicion.
At the time it wasn’t clear to me if there was any substance to the story or if it was the usual Internet exaggeration, so I resolved to ignore it for the time being and saved a reminder to look into it after a while.
Now my reminder fired off and I looked around, but couldn’t find how the story ended… do you know?
I’m in a similar boat to you; whether the blobs constitute a security threat seems to still be up in the air. I read through the issue thread on github a few months back and it seemed the vast majority of the blobs were built by scripts contained in the repository, but some weren’t documented well, leading to uncertainty.
The comment by Long0x0 on Aug 05 lists a lot of the blob files.
