It's pretty obvious to most of us that "integrating the group more deeply across its research efforts to help the company achieve its safety goals" is the corporate spin for what was actually "disperse the group that thought its job was to keep Altman himself accountable to safety goals and replace them with a group that Altman personally leads".
Eliminating Ilya's team was part of the post-coup restructuring to consolidate Altman's power, and every tribute to "safety" paid since then is spin.
