The company I used to work for was aggressively not renewing leases that they no longer needed given lower office occupancy. I have no doubt that companies trying to force people back into offices have some pretty silly reasons for doing so (including pressure from local governments) but the idea it's all about execs propping up commercial real estate seriously makes no sense even if it satisfies some conspiracy theory impulse.

Right, but the reason this theory doesn't make sense is because why would the executives of another company give a shit? How would they induce a bunch of tenants to RTO on their behalf?
