The lot of (partially scary) binary blobs is still an unsolved issue: https://github.com/ventoy/Ventoy/issues/3224

As in yeah there's precompiled binaries in this. But it's audited and each binary itself has a link to build instructions. What they are not doing is actually building everything from scratch in their build process. Ok that's a pain to do and i get it. But... i don't see anyone slipping in an unaccounted for binary here right? If every binary itself has a "here's how to build this from scratch" documentation and source it seems ok to me.
