Guys, calm down.  

The code you posted doesn't send your username to bitcoinarmory.com, it sends the truncated hash of your user home directory path.  This does not give us any information about you except that it will be the same when your system makes multiple requests for version/announcement information.   We intentionally chose this instead of tracking by IP because we knew that IP logging was "not cool".  And in the end, we don't care about your IP, we only use it the ID for collecting statistics about what operatings systems are being use to run Armory and what versions people are using, especially after announcing new versions.  This helps us remove duplicates.

Armory (the company) only tracks unique IDs long enough to collect daily statistics of our user base, like how many people have upgraded.  If a announce-request is made and comes from an ID we have never seen, we add the OS and Armory version to the statistics.  Otherwise we ignore it.   That's it.  We added the unique ID so that we have a way to count unique users without logging IP addresses.    We also add the ability for you disable this by running with "--skip-annuonce-check".  

As a company, we have to have some way to measure our userbase, and we felt this was the least intrusive way possible.  And you can opt-out.
