Google Pack changes

Recently noticed that Google Pack does not contain following software any more:

• Ad-Aware
• Adobe Reader (renamed)
• Symantec Anti Virus
• FireFox (why?)
  

But it still includes some of the third party software such:

• Real Player
  
• Skype (Isn't Skype competing against google in some or other way? may be it is on acquisition list)

Do not know why!!!!
