Back when Oracle acquired Sun, you really didn't think that it was going to continue with the free open source model, did you? Of course not. This is Oracle, and Oracle is all about business. It has expensive products and even more expensive support and maintenance terms. And if someone like SAP starts to offer cheaper support, Oracle has the legal resources to sue them out of its turf very quickly.
Those lawyers are now busy suing Google over Java license violations in its Android platform. Meanwhile OpenSolaris is seeing its last days in the sun as the focus shifts to its commercial counterpart, Oracle Solaris, where there's money to be made.
It won't be long before Java, MySQL, and OpenOffice will be history too, at least in terms of their current forms. In Oracle's world if a product doesn't substantially contribute to the bottom line, it's axed. That's an unfortunate hit on innovation and open collaboration.
Oracle has a good track record of successful business ventures and profitable acquisitions. But the company is basically reliant on old legacy systems from itself and acquired companies to drive its earnings. When is the last time you heard of an innovative or exciting product coming out of Oracle? Probably in 1977 when its flagship product, Oracle Database, was conceived. And even then Oracle Database wasn't that novel. It was based on an existing IBM database product.
