Blocking by user-id seems to me to be the only serious option. You
should have good reasons to believe that a given user is not able to
escalate privileges.

Blocking by executable name sounds somewhat silly, as a program could
still launch, say, curl to do its dirty job.

A different approach could be to find out which servers Muse Group
uses to collect data and block routing to them for the whole system.

(Actually, it doesn't seem that any of these is needed for Audacity.)
