Also, lots of proprietary stuff is available for free or close enough. > You can view the source code There's actually sort of fair, although it only extends to the functions in the language; "Older or core functions written in C are not viewable this way", and I doubt this extends to the underlying engine. > You can modify it Again, provided you stay in the "userspace" parts and don't want to share your changes. > You can contribute ... stuff that you built in Wolfram, but "we don’t really believe in user contributions to the core language". > There is a supportive (and supported) community https://community.oracle.com/hub/ https://social.technet.microsoft.com/Forums/en-US/home Forgive me if I fail to be impressed. > There is active development Until there isn't, at which point the single point of failure suddenly does matter. Also, not much of a standard; IBM still develops Db2, y'know. |
Because this development is sponsored by old customers; I haven't heard about anyone choosing DB2 for a new project.
