@amadeus I think it matters for developers seeing the site, as it means there is source code that can be used/seen as reference.
By that I mean, if a developer sees an issue with their Linux builds but some other random plugin X does not have those issues, seeing that X plugin as opensource is very helpful as then its source code can be studied to understand what it is doing differently.
It also helps in the case of "how do I do X and Y on Linux?" if other devs did it before
