I would add, though I guess it's covered by what I said, that there are situations where it's not clear, as a matter of what's basically legal analysis, which side of a FOSS dual license is actually 'better'. A good example might be the Sun GPLv2 with Classpath Exception | CDDL case -- in the cases where that dual license applies, you can come up with arguments why one or the other license is preferable based on various factors. - Richard On Wed, Jul 13, 2022 at 4:37 PM Jilayne Lovejoy <jlovejoy@xxxxxxxxxx> wrote: > > > > On 7/12/22 8:31 AM, Richard Fontana wrote: > > On Mon, Jun 6, 2022 at 5:51 PM Fabio Valentini <decathorpe@xxxxxxxxx> wrote: > >> On Mon, Jun 6, 2022 at 11:14 PM Richard Fontana <rfontana@xxxxxxxxxx> wrote: > >>> On Wed, May 25, 2022 at 2:12 AM Otto Urpelainen <oturpe@xxxxxx> wrote: > >>> > >> I wonder what you think about simple cases of "effective" licenses? > >> For example, most Rust projects are dual-licensed as "Apache-2.0 OR > >> MIT", but some odd ones are released under "MIT"-only or > >> "Apache-2.0"-only licenses. > >> > >> So, for a binary package that contains code from both "Apache-2.0 OR > >> MIT" and "MIT"-only projects, we usually "collapsed" that into just > >> "MIT". > >> Just enumerating the licenses in this case - "(Apache-2.0 OR MIT) AND > >> MIT" - would be kind of silly, in my opinion. > > I wanted to follow up on this point since it does feel to me like we > > are stubbornly clinging to the practice of recording a FOSS dual > > license in the license tag, when not doing so could provide some > > simplification of license tag expressions. > > > > In my mind, there were a few reasons for this practice: (1) it was > > what Fedora traditionally did; (2) it matches general upstream culture > > (the idea of passing down a FOSS license choice through a chain of > > distributees; (3) there's a contrary corporate culture seen in some > > quarters of making sure that "bad" (from their perspective) FOSS > > licenses in a dual license scheme are eliminated, which I think is > > based mostly on ignorance and copyleftphobia and so forth, which we > > don't want to encourage or be associated with; (4) there isn't going > > to be a good, consistently-applicable basis for selecting one or the > > other license -- this is related to (3).
