Microsoft doesn’t really understand the open-source movement because they don’t empower the end-user. The open-source technology they produce requires certain platforms or licenses to function properly and the data that software generates isn’t portable. Ideally, open-source software could go on any system and function long after Microsoft has stopped providing support because developers are free to reuse, recycle and maintain it. Also, the content generated from that software would be in the format of an open-standard so that users could take it with them after they are done using the software.
