Sun & Novell vs Microsoft

Regarding the recent events regarding Sun & Novell, we could observe the following recent events:

1. Sun settles with Microsoft and "moved to a new phase of legal and technical cooperation with longtime foe Microsoft", in a deal that involves transfer of money to Sun;
   
2. 2,5 years later, Sun open sources Java;
3. Novell and Microsoft sign a deal, with money transferred to Novell.

Looking at the Sun example, it really doesn't sound like this deal with Microsoft will be harmful to their open source efforts. At least I hope I'm right... :-P
