That's somewhat concerning, but without a similar tool as an alternative or a clearly malicious incident I'm probably not going to stop using it any time soon. I only scratched the surface of one of those references anyway, and looks like digging through them to see the discourse and the meta-discourse would take a little while.

If it's a point of genuine concern however, there's always Rufus or Etcher for writing a single ISO at a time, unless they are blob-dependent too. Or dd haha
