I hope we've generated enough good faith with the community that we get a little slack that this was not our intention. I take the blame for not realizing that, and I want to make sure that it is fixed. ASAP. I will happily take feedback on how this should be adjusted so that we can meet our goals without compromising the privacy of the users.
Suggestion: Generate a completely random token upon first run. Store this token in the armory data directory, and optionally remove it upon uninstall.
Bonus points: Make it opt-out during install.
Additionally: Destroy all previously collected hashes. To retain usage data just replace them with unique random values, or an incrementing counter.
