Switzerland mandates all software developed for the government be open sourced

I wonder how this will impact us infrastructure types. I am sure there must have been an exception to the rule at least once in my career but I can't recall any, code I have made for all governments has been open source and if you lost it somehow I would just email it.

My only concern would be the systems that my code runs on top of won't be willing to share. It is one thing to demand it from me, another to demand it from Siemens. Then you add in very low level code for individual devices such as VFDs

I guess the nightmare would be that PLC/DCS/VFD makers would basically be blacklisted and I would have to work around that fact.
