That tweet is from August 14. Since then: "Last updated: October 11, 2022 Building access protocols remain largely unchanged from the spring 2022 semester, with several additional spaces now open to the public including in buildings 32, 76, and E25. MIT ID holders continue to have wide-ranging access to campus buildings; MIT campus outdoor spaces remain open to all.
