The world should wake up from tech dependence. Let the EU massively invest in FOSS.
Edit: as raised by comments, my title was not incorrect but did omit that it’s actually the US that imposed sanctions, to which MS chose to comply. Changed the title.
I get that is what your gornment told you, but it literally is not true and there are plenty of sources to back that up.
Russia, on their own, started developing SPFS almost a decade before they were banned, because they were threatened with a ban in 2014 if they didn’t stop invading more after Crimea. So when they invaded again they were rightfully banned.
The SPFS functions with some banks covering about 15 countries, hoping for 20 soon. SWIFT is still happily used by over 200 countries.
