Thankyou for replying. The point is: how do I verify that I have a
legitimate download of the GNU Emacs Windows binaries?

I have an informal trust path to
28D3BED851FDF3AB57FEF93C233587A47C207910 because https://www.gnu.org
mentions it. No such statement exists about
835224047598ECBC61A1DA345FE9658D60C3B396.

The web page told me to send comments to bug-gnu-emacs@gnu.org, and so
here we are.

Is there some more appropriate reporting channel?
