Oracle has already bagged the U.S. regulatory approval to acquire Sun. If the Europeans go along as well, Sun will become a part of Oracle by September. That means Oracle will also own Java, the popular open source programming language used widely on the Web.
Today while installing a Java upgrade I was presented with an option to install the Bing toolbar. As you know Bing is the much hyped search engine by Microsoft. As you also know, Oracle and Microsoft are rivals in several industries, the biggest one being the database industry. That will just get bigger when Oracle takes control of MySQL (also owned by Sun.)
I wonder if Java users will still be given the Bing option after Oracle acquires Sun. Then again Sun and Microsoft were themselves pretty big rivals until a few years ago. Passage of time makes strange bedfellows.
