Your first sentence misrepresents what the Apollo dev said. Actually, it's the exact same misrepresentation that the Reddit CEO knowingly made in public.
First off, it's abundantly clear that the Apollo dev wasn't actually demanding money. It was a pointed statement that revealed the CEO wasn't being honest about the costs.
The CEO, in contradiction with publicly available data, claimed that Apollo was costing Reddit $20 million per year in lost opportunity. So the dev jokingly offered to sell Apollo for half that price. Then Reddit would be able to recoup the cost in half a year and gain an additional $20 million yearly. What a great deal, right? Except they both knew that the $20 million price tag was complete bogus.
