# Examples
Note that some of these examples are still just pointers that will
need followup.
* The license now named the "Bootstrap Open Source License" (BOSL) was
formerly known as the "Transitive Grace Period Public Licence"
(TGPPL).
The 2020 blog post [Introducing BOSL, a radically new type of
open-source
license](https://electriccoin.co/blog/introducing-tgppl-a-radically-new-type-of-open-source-license/)
discusses the license and gives some examples of its use.
An earlier (2010) writeup about TGPPL from Ted T'so is
[The Transitive Grace Period Public Licence: good ideas come
around…](https://thunk.org/tytso/blog/2010/01/20/the-transitive-grace-period-public-licence-good-ideas-come-around/).
[Tahoe-LAFS](https://github.com/tahoe-lafs/tahoe-lafs) seems to have
a somewhat complicated (though still open source) licensing
situation, but it appears to be also published under the TGPPL?
And Zooko might be using BOSL or TGPPL for other things as well.

Fontana is in the commit history there.)

(creator of LLVM, Swift, and XLA/TensorFlow).
The situation with GitLab is interesting. They make some fairly
specific [public
commitments](https://handbook.gitlab.com/handbook/company/stewardship/#promises)
that are somewhat DOSP-adjacent but are not themselves DOSP
promises. They also say they [default to moving features
"down"ward](https://about.gitlab.com/company/pricing/#default-to-move-features-down),
which in their nomenclature means toward the FOSS product; while
that's not a binding commitment, they do seem in practice to be
sticking to it.
Overall, there does not appear to be an true DOSP activity here, but
their way of operating probably warrants mention in the Appendix, as
people interested in DOSP would also want to know about this.

* North Road (geospatial software company) [projects](https://north-road.com/#)
@jjgreen followed up in https://news.ycombinator.com/item?id=37745772
to say: "North Road's SLYR (ESRI to QGIS Compatibility Suite) does
that (and rather good code it is too). https://north-road.com/slyr/ .
I see North Road is actually on your list, but eventual openness not
obvious. I think that's clear for SLYR at least."

see also https://v2.onivim.io/early-access-portal and
https://github.com/onivim/oni2/issues/3811#issuecomment-910306404 for additional
history
* Android (Google's eventual publication of changes to AOSP)
If Google has typically been pretty regular about releasing stuff to
Android Open Source Project, even if they haven't formally committed
to that regularity, then that would be a kind of de facto DOSP.
(Question: do they preserve the commit metadata for commits
originally made in the private repository, so that when those
commits are published, the exact delay between the creation of the
commit and its becoming public can be seen? Karl guesses that they
do preserve all the metadata, but we should check.)

* [OTRS](https://www.znuny.org/en/blog/why) (open source -> delayed ->
proprietary), but one person said that the announced delayed open release
never actually happened.

* [PKMN Classic Framework](https://github.com/mm201/pkmn-classic-framework)
(a reverse-engineered third-party Pokémon game server?) has a conditional
relicensing if the developer's official server instance goes offline in
the future
* Qt (officially delayed releases in the past from Trolltech?)
* "searchcode" server under an "eventually open license" according to the post

by Ben Boyter.
* [Sentry](https://github.com/getsentry/sentry/blob/master/LICENSE)

# Not software
* Rockefeller University Press Journal of Cell Biology has a delayed
open access policy with delayed relicensing of academic journal articles
(although the end license is a noncommercial Creative Commons license
so it would not be considered open source)
* Maybe there are other examples of delayed open access in journals with
formal relicensing that would be considered fully open source (if the
articles were software)?
# An annoying nomenclature problem
Even though we seem to think that the Business Source License should be
called BUSL, most of its end-users seem to refer to it as BSL! It
may be awkward if we end up having a ton of citations where we say
things like "the project FooWare announced it was using BUSL in 2022
(see 'Announcing FooCorp's Switch to BSL')".
I (Seth) think there's a distinction to be made between these three cases:
* "automatic": licenses that are not open source licenses but that state
(in the license text somewhere) that they automatically convert /
automatically permit use and redistribution subject to a specified
open source license after a period of time
* "manual": publicly announced practices of manually relicensing old codebase
snapshots on a particular schedule, which depend on a person at the company
explicitly making a delayed open source release
(In some sense, this is a potential distinction between a "delayed open
source licensing business practice" and a "delayed open source license".)
* "post-hoc" / "unscheduled": proprietary software that eventually was
relicensed under an open source license, without a public statement of
intent to do so at the time of its original publication, or without a
published schedule for the conversion
I would include the former two in the scope of the report but not the
latter one (except to explain how it's different). Some people have been
suggesting some of these cases (which can be fairly famous, like Netscape
Navigator!), but I think these should be thought of as more of a one-time
"change" than a "delay".
Look in the follow-ups in these threads (and subthreads thereof) for
more examples. Please add other threads here too.

a really good post, in Karl's opinion, not that anyone asked him,
but hey, if you're editing the notes file then you get to insert
your opinions.)
