Comment Open Source in Procurement (Score 2) 96
Around the time of Horizon Online appearing in 2010 (not original pre-2k Horizon), the UK government, also the sole shareholder of the Post Office, was at the cutting edge of bringing open source into public procurement and increasing technical transparency.
What surprises me is that, at this point, there is very little questioning of whether single-purpose government contract closed source is automatically the right choice - there's a case for open and for closed, but Github is a lot easier to access for an expert witness. While there were also issues with the reference data, it is hard to think of a starker example of why having access for third-parties, even just to the code, matters (yes ironic, but did a Medium article few days back if anyone wants some more context links for this point).
This has become my go-to answer to "whether government money means public code only impacts technical people".
