I'm sorry, but an iOS app is made for convenience. Nothing more. Email, social networking, instant messaging, collaboration tools, productivity tools, office suites, development tools, and even entire operating systems are available for free. There is every opportunity for someone to "participate in society" without illegally obtaining something they don't want to pay for. The developer is the creator of the app, and he or she is the one who gets to decide whether you can try it for free. There is no other way to support the developer than paying for their work in some way or another.
