NGOs with foreign funding have to be marked as "foreign agents" in Russia. It sounds almost like "foreign spies" due to a strong tie between these words since the times of Soviet propaganda. It's done to make them very unappealing for an average citizen.
The bumsex is now more in danger than ever. If a federal law that forbids gay propaganda passes, then any public discussion on the matter could be viewed as such. Especially, if opposition tries to protest about this law and related issues.
It's a new threat to what little remains from ever-degrading freedom of speech since early 2000s.
