Is there a mechanism or service that allows me to offer my work under non-free terms, but guarantee that some time in the future, the work automatically becomes open source?
For example, could I release something under license A, but also under a free, irrevocable license B that only takes effect after the year 20XX?
Or is there a well-known service, who will distribute my work under a free license of my choosing after an agreed date?
There are a few motivations for doing so:
- Perhaps I want to monetise my work in the short term, but would like the work to become free at a date sooner than copyright limits
- I want to add value to users by guaranteeing that the work eventually becomes free and maintainable by volunteers, even if I get hit by a bus or I go bankrupt
