No problem at all about your English–I understood you perfectly. Yes, it is true that Outernet is a one-way data broadcasting system. A two-way system would be incredibly expensive. For example, the VIASAT-1 satellite which provides 140Gbps of bi-directional communications to end users costs $500M, not including launch and insurance.
The way to think about Outernet is like you think about Youtube versus broadcast television. They both serve very different purposes and are useful in their own ways. And as a note, broadcast tv (just the distribution of content, not the product of it) is much cheaper to operate than Youtube.
