Answering to the request for feedback on the Guidance on the Implementation of Plan S, we here, as a group of individuals interested in the future of Open Science, provide our perspective. We see Open Science as the approach of doing sound, innovative scholarly research (not just sciences, but also humanities, etc.) that opens up research and does not exclude people. Open Science encourages this by starting from three fundamental freedoms of open research: research outputs can be reused, can be modified, and the modified and unmodified output can be shared with others - without restriction. In doing Open Science, authority and standards do not have to be enforced with copyright law, such as non-derivative clauses, but can be set by community standards; just like attribution (i.e., citation) is a community standard.
