I agree. It seems like 500px is trying to think outside the box to communicate the intentions behind their ToS so that the experience is more transparant. I would assume the thinking is that either almost nobody will read the ToS as is, but maybe some people will actually read the simplified version. The issue of course is that legalese is dense and a simplification is not adequate. As an alternative, I would like to see how people react to a simple statement BEFORE the ToS that explains the company's intentions as an introduction.
