If I were predisposed toward conspiracies I would definitely be convinced by now that every medium-to-large business owner in the country was part of a secret cabal who made a pact to demand return to office for whatever terrible reason sounded good to them.
My own workplace is mandating a hybrid model for any employees within 30 miles of an office after "much research, discussion, and debate with employees." They've typically been very reasonable and generous to their workforce, and I just don't understand what they're thinking, honestly.
