It takes a lot of education. Computer science was actually very slow in moving to the arXiv. The "open" way that people in the field used to use was to link to pdfs on their homepages. An utter disaster for discoverability and archivability. Researchers move around all the time. But this was the standard! It took years for a critical mass to develop such that publishing to the arXiv became the expected standard.
