What the commenter is saying is that this is no risk at all because $14B is negligible money for Meta at a year-long scale. It can always be written off as an investment that didn't work. In a company with $1.73T market cap, this is sometimes the loss you get in a single day of trading.
Yes, $14B can be considered negligible, but it's a signal. My bet is that it's not a great one. Wang has been great at courting clients, time will tell us about how that translate to leadership.
