Well if they say “we will open source the algorithm” and then what they really open source is a little bit of slightly relevant code that doesn’t allow us to understand the algorithm, then what we can deduce is that they are trying to weasel out of public commitments.

I can’t say for sure if that happened, but if they made a clear promise and then did something else, it’s perfectly reasonable to call that out.

Devil's advocate though: imagine you were to open source (probably with quite a short deadline) some 'algorithm' used in whatever you work on, but the rest should stay private; how would you go about that?

I don't think it's easy, there's inherently some interface(s!) where it's a hand-wavey 'get the thing from the private bit', and defining that sensibly is hard, and if you try to do it well will probably lead to a lot of meetings, scope creep, etc. - and as far as that goes it's not easy anyway, since it's highly technical and implementation-specific yet also a management/policy decision to make.

It depends on what your goal in open sourcing is. Are you looking to provide a base for others to build software on, and to provide a way for others to contribute back to your code? Then publishing the code makes sense.

Are you looking to build public trust in you and your organization? Then dumping a bunch of code with no context isn't going to help much, as it's not code but behavior that builds or destroys trust.

Are you looking to lean into a polarized partisan environment, pushing a narrative where its you and your supporters against an unfair group of "others"? Then a big splashy move high on symbolism and low on substance that will inspire lots of high profile, divisive media coverage is a great way to go.

If you were doing it in good faith, you wouldn't need to publish the actual code. Most likely you should publish an article and a flowchart explaining how the algorithm works. Publishing a partial chunk of code just creates a story that supporters who don't understand can parrot that "they opened their algorithm".

Exactly. Publishing what they have is the worst of both worlds - hopefully people will create flowcharts based off it, though, although it sounds like there will still be a low level of accuracy.
