Adobe Creative Suite 5 (CS5)
When released, Adobe Creative Suite 5 installed Growl without informing the end user. There was no mention of Growl being present in any documentation.
About two weeks after CS 5 was shipped, end users started contacting us regarding this situation. We had not been informed by Adobe of this action either.
Adobe documented this problem in an article in their knowledge base explaining what notifications CS5 sends and how to remove Growl. They have also published a blog post all but apologizing for installing Growl on users' systems without permission. One year later they confirmed that Growl does not get shipped in Creative Suite 5.5 after we brought it up on their forums.
