I wouldn't go that far to recommend non custom gov software to be open source (mainly because its far less realistic), but custom should be mandatory. There are very few countries that request that now AFAIK - Romania I think on state level, and many on city/region level. Yes, use oracle junk instead of postgre if you want, but software MUST BE open source, its only logical given that is financed by the budget and analyzed, tested and influenced by the gov people. Otherwise, you have private companies that get rich on taxpayer money, and not only that, but monopoly, zero reuse between regional local govs, worst quality and security etc. You wouldn't believe the resistance I have, trying to introduce this in my country.
