I expect there will be people who reply to this comment to argue it should be "E-T-C" or "Et Cetera". You can ignore those people; they probably say "exclamation mark" instead of "bang".
Not really a big difference in meaning or tone, if you ask me.

The passive voice, combined with the opening phrase, gives the false appearance that the subject is the pronunciation of ‘/etc’, when the true subject is you. I put it the way I did because it is a good exercise and because I didn't want it to seem impetuous.
