When Infoflows put up its public Web site in January 2007, Corbis filed suit, claiming any Infoflows digital content-tracking product would be illegally using Corbis's proprietary technology.
For example, IBM InfoSphere BigInsights analytics software starts with open-source project Apache Hadoop, but substitutes its own file system and adds other proprietary technology.
Even though you can build flexible architectures with proprietary technology, it creates vendor lock-in, reduces flexibility in future sourcing, and likely results in higher total cost of ownership.
