I don't have enough time to investigate this but this already stands out to me as bullshit by the IESF
Under their general statutes regulations:

Article 5: Non-discrimination and Promoting Female Participation
The Practice of e-Sport is a fundamental right for all.
All parties related to IeSFs events including its Members and partners shall take all appropriate measures to eliminate discrimination against women, and to promote and elevate the participation of female players in order to ensure, on a basis of equality of women and men, the same rights, in particular, to participate in recreation, leisure and sports activities and all aspects of cultural life.
Discrimination of any kind against lineage, gender, religion, politics, individual, organization or any reason is strictly prohibited and punishable by suspension or expulsion.
Under their competition regulations:

Article 10 Official Title
The Official Titles of The World Championship are as follows :
Four Official Titles for the The Tournament shall be designated by IeSF:
▶ Male Division: Two Titles (regardless of team or individual match)
▶ Female Division: Two Titles (regardless of team or individual match)
Honestly the tournament organizers I believe are still given the lattitude to have mixed gender divisions because of.
The OM Shall have the right to recommend two additional Official Titles as regarding the preference of the host city/country.
