@BioSchweiz @webmink @maemst from reading the german language link (2 clicks in) this is about digital sustainability: an application that is developed for a government agency (city, federal etc...) must be OSS so that it can be reused, maintained, repaired and improved (by the govn) without license restrictions. OGD (data) is also open, except if personal data. But purchased MS software is not bespoke. Maintenance, upgrades, and longevity are provided by the supplier.
