Hey, if he WERE making that much money, more power to him. I'm all about getting paid for hard work. But, $96,000 per month would mean that he's selling 1,600 copies of ST2 per month. That's over 50 licenses per day. I'm not saying he isn't - but that does seem like a bit much.
Ultimately it doesn't matter. The issue at hand is the cost of the editor. I don't think it's expensive but as someone else pointed out, it's all relative, so we're in the world of opinion which we could argue about all day. Here's a thought: Call of Duty Black Ops 2 raked in over 500 million in 24 hours (at $60 bucks for the standard, non-collector's edition). That's over 8.3 million copies sold in 24 hours. That's 8.3 million people who don't think $60 bucks is a lot to spend on a game. Why should it be a lot to spend on any other software? And we're back to opinion.
I do want to mention that I'm not intending to criticize anyone for their opinion, so I apologize if I came off that way.
