The ruling itself is much more nuanced and covers a lot of situations, including extremely rare disorders of sexual development (DSD) and their variations. The most recent controversies on this topic did not involve transgender athletes, but that's largely unknown or misunderstood by people who only know this topic by headlines and sound bites.

The headline writers are relating it back to the topic which brings the most clicks, which is transgender athletes.

The IOC didn't go on a crusade against transgender athletes specifically. They were refining the rules on sex-based divisions and included a lot of considerations and nuance.

Not quite. Only male athletes who have male physiological advantage. A small subset of male athletes with specific disorders of sex development that preclude this advantage may still compete as female.

The former is included in the latter, so while inaccurate it's still correct.

Just as cis women can have the SRY gene, so too can trans women not have it.
