I honestly take most of my info from Reddit. There are a couple of subs where the discussion is quite nice. Twitter has a steady stream of data coming in and OSINT channels seem to make a honest effort to present genuine data (even if one-sided).
There is also the confirmation from the British Ministry of Defence: https://twitter.com/DefenceHQ?ref_src=twsrc%5Egoogle%7Ctwcam...
They are Ukraine aligned but are IMO more trustwordy.
Overall, I admit the fog of war is thick. But even maintaining my skepticism, the info seems coherent enough to convince me.
Just saying "You cannot base opinion on online media" is useless because what are YOU basing your opinion on? Online media, written media, whatever.. it's all information, one way or another we're all basing our view on external sources. The trick is filtering it and I think it's possible to at least glimpse reflections of the actual status. If you don't take into account any information you know nothing and just go off on projections in your head. Much worse state of afairs.
