Basically they've taken a step further with censorship of all media not controlled by government which at the time (2014) couldn't been penalized whatsoever.
"Couldn't be penalized whatsoever" wasn't enough? In broader view, government could start taking hostages like they did with Google last December, but that wouldn't help reaching the goal even a small bit back then since there was no leverage on technical side of things.
> What's the alternative? Open rebellion against the state?
Yes. HTH!
To elaborate: At some stage, that becomes the only acceptable alternative; not doing so is morally culpable.
The world learned that in 1945, two ways:
1) "I was only following orders" was deemed not a valid excuse at the Nürnberg trials; not refusing orders like that is complicity; and
2) Germany as a whole was de-Nazified. Just like Russia needs to be now. (But more thoroughly: in Germany's case, it was an aberration of a dozen years; in Russia's, it's a millennium of unbroken history of totalitarianism.)
Too bad the world seems to have forgotten those lessons since then.
