Once the cutting has started the company is unlikely to have set the morale/team/event budget large enough to support go kart outings. That or the entire years budget would be gone at once.
There's a difference between having fun at work, and having fun allocated by work. What most companies have is enforced fun - once or twice a year you'll go to an offsite location with free booze and try some ridiculous forced activity, and the desperate hope from corporate that that can take the place of actually enjoying your job. What most companies want is an atmosphere where people have fun and are passionate actually doing their job. That's what you see in these early annual reports from Netflix - people enjoying what they do. Now, in reality in business sometimes the imperatives change, but that doesn't make those two things the same.
How many people earnestly find fancy reports fun, and how many are just smiling and playing along to avoid being a wet noodle? In the case of Netflix, it was apparently one guy's passion project. Great for him, but how many netflix workers really feel like they're having less fun now that he's not doing it?
