One big problem with visibility is the abysmal track record of state bureaucracies, at both local and national level. Local ignorance will not shift unless and until central government blazes the trail.
David Cameron's Cabinet Office moved heaven and earth to open up Departmental usage but was defeated by the tickbox culture. State bureaucracies have lists of approved suppliers. With very few exceptions, FOSS providers are not on those lists. Updating the list is a massive exercise in consultation and visibility of fair process, it takes years. But a) it is never a priority, and what state bureaucracy ever has time for its mere ToDo list. And b) the exercise is invariably administered by contractors supplied from commercial companies, who scrupulously exclude unreliable products from the lists, and of course the OSS competition is argued off the stage.
And of course, when you pay good money, you buy yourself a scapegoat. Approve an OSS solution and you cannot duck the blame if the proverbial hits the fan. So what good pension-builder would ever risk losing their scapegoat? The Cabinet Office tried to introduce a presumption of OSS unless only a commercial offering met the requirement. Suddenly, security became a requirement, along with the dogma that OSS is inherently insecure. All OSS fell at the first hurdle.
Yet some corners of some Departments do use OSS quite a lot, and would very much like to feed tweaks back into the community. But no, everything a civil servant writes is Crown copyright and may not be released under a permissive license. And that includes computer code. As a way round that it is possible to commission code from a contractor on any license you choose, but then you hit the "not on our list of approved licenses" wall that accompanies the purchasing tick list.
Back to Square One.
The only way to get things changed is to change statutory law, to allow Departments to reassign copyright in the public interest, to limit all State lists of approved suppliers and licenses to a finite life, to require all proprietary software purchases to be signed off by the Cabinet Office until the culture change sinks in, and to require all Departments to set up and empower an OSS adoptions and contributions office. Only then will we find out what I have missed off the list.
