Maybe they are betting that putin can’t use nukes because it would imply Article 5, and that the Russian army is spread too thin for them to curb their uprising.
But take everything I said with a grain of salt, I know nothing of geopolitics or russian culture.
After nearly 4 years working on generating fake news, operating an army of fake accounts with a few dozen of more "real" like accounts, running an online newspaper that is the fifth most visited online newspaper in it's country (and I don't even speak it's language), let me tell you something that is the only thing you need to know when you are browsing the web - don't believe anything you are reading online.
If Putin gets desperate wouldn't he just start using heavy weapons? Doesn't Russia have a history of disregarding their own populations lives?
So what is this guy doing rising up?
