[gentoo-nfp] Social contract and its effect on upstream software choices

[Alec Warner]

Hi,

Consider a case where we have a piece of software and its open source. The
open source software has various plugins, some of which look useful and we
may wish to deploy them for Gentoo. However, we must consider the social
contract, hence this discussion.

Can we use the plugins if:
 (1) They are closed source (e.g. upstream provides binaries only with a
restricted non-free license.)
 (2) They are free software (e.g. FSF / OSI approved license) but they cost
money.
   (b) A subset, its free software and it costs money but it is free for
open source communities to use.
 (3) They are open source, but not free (e.g. they have some kind of open
license but are not FSF / OSI approved.)
 (4) They are open source (and free), but we have chosen to use the built
plugins (rather than building from source) for the sake of time and
convenience.

Which are allowed, and which are not?
