Another good portion of the hate comes from the fact that you're selling projects that are not open-source as open-source.
Maybe it's just me, but if you're running a slimy code-selling website you should at least know better than to call it open-source. Here's a link you should read before you get sued by the OSI, which I will be kind enough to not charge $750 for: http://opensource.org/docs/osd
I'm also curious why you think integrating a PDF reader into your app costs $36k. In my world we just use a UIWebView. Or, if you want to type maybe five more lines of code, you can use CoreGraphics. You can then spend the $36k you save to get Donald Trump to fire your horrible developers.
Finally, you probably want to fix the grammatical issues in your laughable "commercial open-source" license if that's a core part of your business.
