It appears that Nexenta's edgefs code was open source under an Apache 2.0 license at least as far back as 2020-03-12: https://web.archive.org/web/20200312165928/https://github.com/Nexenta/edgefs https://web.archive.org/web/20200312165928/https://github.co... ... and probably further back too - here's an HN post referencing the licensing from around Q3 2019: https://news.ycombinator.com/item?id=20671417 https://news.ycombinator.com/item?id=20671417 I hadn't heard of DataDirect Networks before; it looks like their acquisition of Nexenta closed in May 2019: https://www.theregister.co.uk/2019/05/07/ddn_is_buying_nexenta/ https://www.theregister.co.uk/2019/05/07/ddn_is_buying_nexen... "Nexenta by DDN will be run as a separate entity, retaining its own sales and engineering teams. The Nexenta sales people now get a wider DDN channel to use and there are cross-selling opportunities for both." As far as I understand -- I'm not a lawyer -- changing a license requires that existing contributors are notified and agree to the change of licensing. https://softwareengineering.stackexchange.com/questions/55326/can-you-change-a-license-once-you-pick-one https://softwareengineering.stackexchange.com/questions/5532...
