Well, making it without proof is a shallow defense.
People do care. And this is a basic trust problem inherent to computing.
Ever notice how there is often redundancy and history present?
This is why.
Another place this shows up is electronic voting. Lack of personally identifiable records leave people in a position of forced trust, unable to know the record is accurate.
Motive plays a role here.
Spez had a childish, bigger dick type ego motive. Untrustworthy.
The same exact thing done to protect someone, and done with rational communication would be far less controversial.
As for the hard drive, the defense must speak to motive and it must be compelling, or we are all likely to trust the person doing that necessary work.
Your comparison is germane, but too simple, in my view.
