Why did Cardinal Cupich prohibit Traditional Latin Mass on First Sundays?

Cardinal Cupich ordered no TLM Masses on several days of the year: > The new policy also prohibits the celebration of Traditional Latin Masses on the first Sunday of every month, Christmas, the Triduum, Easter Sunday, and Pentecost Sunday. https://www.ncregister.com/cna/cardinal-cupich-issues-new-restrictions-on-traditional-latin-masses Other than spreading confusion and chaos, what reason could he have for preventing TLM to be celebrated on First Sundays? I've heard of First Fridays, I've heard of First Saturdays, but First Sundays are new to me.
