Sun is now Oracle.
No, Oracle bought Sun. There is a big difference because there is a huge difference in company culture and strategy. If Oracle didn’t buy Sun this never would have happened. Sun had a certain philosophy about Java. Can Larry Ellison decide he wants to put the genie back in the bottle? That’s why what Sun’s position before Oracle acquired it is important.
For example: If Ellison somehow bought Linux tomorrow, could he start imposing royalties on users? He’s not supposed to, but that’s kind of what he is doing here.
