It's quite close to non-existent. The Kremlin has a very efficient propaganda and disinformation machine. The Kremlin has full control over television, media and newspapers, with the Internet being the only relatively free resource where different opinions may exist and co-exist.
The Kremlin is now actually launching a huge campaign against important independent Internet media. The most recent news is that they've designated Meduza, the largest independent news outlet, which is based in Latvia, in Riga, to be a “foreign agent”, which is a very nasty designation, because it in fact prevents any advertisers from working with them. It influences the media in a very bad way financially. Also, of course, if they manage to kill Meduza, they will go after everyone else.
Meduza is now trying, for instance, to launch a crowdfunding campaign. Hopefully, they will be able to collect enough donations to keep going, to kind of reimburse them for the loss of advertising, but of course it's a very hard time for independent media. That's on the one hand, but on the other hand, we see a boom in investigative journalism in Russia, for instance. People are really trying to find independent information, so more and more people are turning away from the television because they realize now that it's all propaganda. People are actively looking for independent dissenting opinions online.
One last thing—very short—is that what's really important here are the positions that the major Internet platforms will take. Technically, the Russian government has passed a bunch of laws that make any sort of anti-Putin publication on the Internet illegal, of course, and they impose huge fines on Google, Facebook, Twitter and so on for not deleting this information. So far, Google, Facebook and Twitter are not caving on the this. At times they pay these fines, but they don't delete this information. If they manage to carry on, that would be okay. If they start to cave to these government requirements, this will have a devastating impact.
