Russian-speaking citizens don't really want to study Russian as an "elective subject". They want to study in Russian. You have confirmed that it was getting no longer possible.
That's like forcing all Canadians to be only taught in French and subsequently losing Vancouver to the US.
So you have just confirmed everything that propaganda was talking about and were quite efficient at that.
The thread started by whimsicalism stating that Russian was banned in Ukraine, and I replied that it had a status similar to French or German in the US.
Nobody has ever banned a language by allowing printing in it, allowing grades up to 4 to be taught in it, allowing secondary schools to teach it as a subject, and allowing private groups to continue teaching it as a primary language.
