Also, it should be stressed that being forced to be immersed in "office culture" is something that is not in the interests of some employees (somewhere between "most" and "all"?)

I mean, who really cares about all-hands and fireside chats and musings from a random higher-up regarding random facts? Are they better than being close to your loved ones or your pets or wear slippers or even vaccum a room? Get a camera and post them in your blog. Don't force a small army of people to sit around being force-fed whatever thing you have to say.
