Lots of leases are for 7-10 years, sometimes more. They're likely contractually obligated to keep it for now. The sunk cost on that is at least part of the reason why RTO was being pushed so hard.

Tons of office leases have expired since lockdown times and weren't renewed. Not a lot of them left, and that's why RTO mandates have waned. Still get a few "the cruelty is the point" people like what's in OP.
