I don't think this runs as an argument. The downloaded file is, as far as
I understand it, signed by the "logger", rather than by the downloader's
computer, which makes checking for "fiddling" quite easy.

The developers can invent any key-pair they choose. The keys used in the
instrument will have been be hard-coded, therefore the private key is
already in the user's possession, even though hard, if not impossible(!?)
to read...

Potential cheats would need some considerable technical skill as well as
criminal(?) intent. Do such people fly gliders?
