Yeah, I use SysInternals stuff every day. Neither myself nor the community has vetted SysInternals tools any more than they have vetted outlook, teams, or word. Unless I’m misunderstanding the meaning of vetted.
Vetting in a program/application context as I understand it is that the code has been vetted, which can only be done by the community at large if the source code is provided. Just like with a person, vetting is doing an actual background check, where as vouching for someone is just one person telling a second person that a third person is chill or something.
