With thanks to stopBADware.org and others who complained, Apple has made an improvement in their update practices. Last month, I questioned whether Apple was Turning to Foistware Methods. Based on the example provided by stopBADware.org, at least the updates are separated from the "new software". This isn't a perfect solution, however, it is much better than the way it had been handled.
See Apple Responds to Community Concerns at stopBADware.org for an illustration of the changes made by Apple.
