That's the only potential downside i can see: because the landlord company is big, it will by nature become very conservative with the (working for hire) bosses being too cautious as to not goof up their jobs, with a huge bias on preventing failures as opposed to enabling success. So they may indeed tend to ban more and more "unsafe" or "morally objectionable" activities to please everyone, eventually making the place too boring to stay in.
