I've not knowingly let anything with "Sony" written on it directly touch machines on my home network since. People think I'm weird...
I do remember seeing an apology and promise from Sony about the incident in the form of a press release. Though my reading of it was "we are sorry they got caught and embarrassed us" and "we promise not to do exactly the same thing in the near future" (which left them open to doing something just as bad right away and open to doing the same thing now, years later, without breaking their word).
