It's meant to deify these CEOs. Gullible schmoes see this and think "well that makes sense, he spends every hour of his day working. That's three times more than me! No wonder he makes a million times my salary! See, the only reason I'm not making billions is because I don't have the divine skills and talent to work on my company all day." (Or, "I choose to have a work-life balance cause I don't mind making a little less money")
These CEOs have PR teams dedicated to slipping out stories like these so it keeps the CEO looking like a king.
Especially because the app is called "tea", like the slang term for gossip. The letter of the intention may have been good but the whole thing is toxic.
