Lodsys, the company threatening to sue some iOS developers over in-app purchases, has made a series of blog posts attempting to defend its actions. Regarding why it is targeting developers instead of Apple -- the company responsible for creating iOS' in-app purchase technology -- Lodsys downplays Apple's role. "The economic gains provided by the Lodsys inventions (increase in revenue through additional sales, or decrease in costs to service the customer) are being enjoyed by the business that provides the product or service that interacts with the user," it writes.
