If you take a look at XP activation, Office activation and more software's doing very odd things such as ADS (alternate data streams) what you end up with is that the archive program feature was failing better than 2% of the time.

-> This created support calls that the consumer would pan the product for failing to archive and restore said software programs.

It's for this reason that this feature had to go. It was becoming unreliable as more vendors implement features to press the issue that you must install the software from the original CD.

You may not like it, but Symantec wasn't the reason it had to go.
