Calling a detention facility a Nazi concentration camp is not the same as calling a grassroots effort a "telegram revolution". One is making an analogy to history, the other is using a vapid phrase to market a mobile app.
In fact it is a Telegram revolution, because Telegram is the tool that is allowing this rage to become organized. That doesn't minimize anything about the protesting or the political situation itself. That's not marketing, it's just recognizing the tool.
