Somewhere in 2018, it was a big deal when Chinese company Creality made their Ender 3 printer 'truly open source', as acknowledged by the Open Source HardWare Association. See for example this YouTube video by Naomi Wu.
When the Ender 3 V2 came out, the upgraded version of the Ender 3, I'd thought the Ender 3 repository would be updated with the new files. However, this never happened.
Considering the speech by Naomi starting at 1:10, I'm quite surprised by this. But after reading their GPL license, I can't see them doing anything wrong either.
There is the following requirement from OSHWA:
Ensure that all of the creator’s own contributions to an open source product using the certification mark are shared as open source in accordance with the agreement and these requirements.
However, I'm not sure how a new version works with respect to keeping the original license intact or whether this is a derived work. This could all be a matter of misunderstanding based on the definition of the work and the license.
- Am I correct that the files of the Ender 3 V2 were never released?
- Were either the GPL-3 or the OSHWA requirements violated by releasing the V2 without releasing their files?
Or, perhaps more to the point, does the license of the original work still hold on the V2?
