I do get why people are upset about it, and agree we should try to make it clear to Nokia that it was a poor choice, and should not be repeated. But griping on a forum they don't monitor won't change their behavior. If you want to make a point, organize a letter writing campaign or setup a date/time for everyone to call their support like to complain about it en-mass. They need something big and explosive to see how big of an issue this is, not bits on a drive on a server they don't even remember they own.
All this fuss over a number. You do realize that every time your phone gets/makes a call, or an sms, or even an alert back that it's on, the phone and/or the tower you're talking to transmits that number in the clear, yes? All one needs is a radio packet sniffer and about 10 minutes to collect all this information from every phone that's on and within transmission distance. Your number is transmitted and stored all over the place in the clear, it's not a national security secret.
This whole uproar reminds me of how people were upset when they discovered some web sites would "store" passwords in clear text files. At one point I saw someone say they wouldn't use the web server side of a file share, and would only use the ftp site until the "bug" was fixed. Completely not realizing that FTP transmits their username and password in clear text to the server (always has, still does)...
