Siemens Pulls OpenRadioss; Rocky Forks

After acquiring Altair, Siemens removed the public OpenRadioss repository and other community resources; the Rocky Enterprise Software Foundation quickly forked the last public snapshot into a new project (OpenCourant) under the same AGPL license but is hampered by missing binary artifacts. The episode shows that corporate acquisitions can reverse prior open‑source commitments and that community stewardship requires not just source control but artifact preservation and institutional hosting. — This matters because it highlights a recurring risk to publicly relied‑upon open software—loss of access after acquisitions—and suggests policy and community responses (artifact archiving, foundation stewardship, license choice) that affect research, safety‑critical engineering, and industrial competition.
