Instead of being a unique event, it might just be one of the first. All the 'strange event' are just the things we noticed from previous color revolution. But that does not make those revolution any 'less' revolution for the people. People from surrounding countries being inspired and imitating such revolution is not really surprising event.
Using instagram to organize, discord to discuss and Facebook to share also seem less weird if looking from the perspective of Gen z. They are using the tools available to them to achieve their goal, unaware about the dangers inherent to such tools.
Things are really murky on that. I do not know where it even originates from but it could be miss-information. Not really worth going into all that anymore, he has somehow turn most people wary of him after that stated being spread on social media.
Anyway things looking fine here. The pro-US government got oustead and the new government is also 'liberal' but more left than the Marxist-leninist party somehow.
No left really put their hope in a spontaneous horizontal movement with no leadership but it has helped release the pressure building in Nepal I guess.
