not entirely sure but this doesn't feel like something the fsf would like . most definetly it violates freedoms 0. because it discriminates against companies with over 5 M$ in income and against people living in Japan (see 2.14 , though I'm not sure its enough to qualify) , and possibly by restricting what you can do with the software , though I'm not sure on that one . it also violates freedoms 2. and 3. by requiring publicly releasing your changes (fsf requires that free software licenses allow for private modifications) and possibly by requiring contacting the licensor or the post-open administration though I'm unsure of if it does (entering into a post-open source zero-cost / paid contract seems to me to imply contacting either the licensor or the post-open administration) .
