You're talking about the same thing as the article: why were things not as fast as they could be in free threaded mode?
But this comment thread is more of a meta discussion: why would lock contention issues only show up now, in free threaded mode, if numpy already released the GIL anyway? That's what I answered above: yes the GIL was sometimes released by numpy, but these operations really were happening with the GIL locked (in non free threaded build).
