For a good reason. If Snowden published US secrets soemwhere, how fast do you think it will be taken down by cloudflare. wikileaks never had a problem with hosting either it seems, right?
Perhaps you've missed it, but numerous media outlets have published US secrets collected by Snowden. Where are the takedowns you expect against NYT, Washington Post, Guardian, NBC News, etc.?
All these media outlets make a point of saying that they have carefully redacted anything that may put people's lives in danger. I imagine that any site which published it raw would be taken down even in USA.
Remind me, those photos of Guardian destroying Snowden files all over the news sites are clearly because Russians forced them to? Or was it UK government?
Navalny is a political opponent of Putin. He has nothing in common with whole whistle-blowing thing. Blocking his blog is like banning Fox from broadcasting.
