This is exactly what Sun thought. They looked at their licensing bill for using MS Office and thought they could develop an Office suite for less than that themselves. They bought this little German company which made "Star Office" and started developing it for their own use and also selling it. Turns out, it didn't work. So they Open Sourced it, called it OO.org... it still didn't work. 20 years, many rebrands and many changes of ownership later, that same piece is software is still struggling to find a way to exist. Turns out, developing a competitor to MS Office is not that easy or cheap.
