Except you you're purposely slanting the situation so as to position reddit as the "bad guy" and Apollo as an "angel"
1) He has grossed $500,000 a year from subscriptions ALONE
2) Next apple's 15% cut (not 30% you are lying again) - that is $425,000
3) There are plenty of purchases in the app that is NOT a subscription (in fact that's what I purchased - Apollo Pro). Let's even assume it makes 50% of the sub revenue, that's $200,000
4) He has no costs. That's the whole point of this argument. He's been freeloading his server off Reddit's. He doesn't even host the frigging content. I repeat HE HAS NO COSTS.
5) So he has a take home of $625,000 a year. Let's say that it grew linearly for 8 years. That would be 80k+160k+240k+320k+400k+480k+560k+640k = $2.88 Millions Dollars
6) That doesn't even include pixelpal, which he has publicly admit has made more money for him than Apollo itself
7) Someone who has earned more than 5 million is not considered a multi-millionaire? What kind of world do you live in?
