Yes, there are independent mass media, but almost none left on TV or radio.

Social media and other free platforms, no matter how much I dislike the ad-driven near-monopolies, appears to be right now the only way people find 'unofficial' information about the war and express their sentiment by e.g. sharing Hitler quotes with attribution at the end (drawing stark parallels with Putin's speeches).
Russian gov is understandably being dissatisfied with that, and the infrastructure to censor Internet like China does does not appear to be in place. What seems probable in near term is disconnection of Russia. (At Russian government’s initiative, if that is not clear.)
As a Russian, I say do what you will but please do not load a shitload of JS that will make vital information take ages to load on increasingly brittle connections.
