Not sure why you're downvoted (you've since added to your sentence; it was just fine alone though). Twitter's has way too many people on payroll. I personally know some buffoons they hired in the past year or so, and I doubt I'm alone.
I don't know if these kinds of deals cost Twitter money directly (I wouldn't be surprised), but I'm sure their marketing department is the most expensive operation they have.
It wouldn't surprise me to hear some tech company has hired comedians to entertain the staff.
