Obviously, if it were profitable then revenues would have to be substantial - above total operating costs. Any percentage of that would be a massive expenditure.

Whereas if it is not yet profitable, then revenue could be tiny - i.e. you might be 'vetoing' (with your comment) a $50 expenditure that serves to generate huge amounts of free advertising and goodwill for Reddit.

Frankly with this level of analysis, it would surprise me greatly to learn that you have any money remaining to invest.
