One way to deal with that is to let the probes send in the hash value of
its firmware or something similar, which can be used to detect problems
like that.  And you could prepare "official" reports based only on the
probes running "official" firmware.

I really think this is orthogonal to releasing source code though.  If
you haven't built in any security mechanism, people can already do what
you appear to be afraid of today.
