The DPS8M simulator program is using the ICU License.  There are other major programs that redistribute ICU-licensed code such as Bloomberg COMDB2, IBM NetREXX, etc.

Code under this license is distributed with Android (https://chromium.googlesource.com/chromium/deps/icu/+/refs/heads/main/LICENSE).

>>> The chances of decNumber being re-licensed by IBM is essentially zero (or I simply don't know who to talk to), which means that all code that derives from the ICU-licensed decNumber is not under an OSI approved license.  GitLab, for example, is not extending their free "Ultimate for Open Source Developers" for DPS8M and other projects due to the use of "non-OSI licensed" (ICU-licensed code) - they (and many others) will only allow explicitly listed OSI-approved licenses.

>>> The use of ICU Licensed code has come up as well in other projects, where there was confusion as to the status of the ICU-licensed code, and, wanting an OSI-approved license, decNumber code was replaced with other libraries, and finally reverted, a waste of time for all involved.
