I don't know who he is beyond anything in general. I've only randomly seen him around the internet here or there. I don't know his full back story. But on this particular subject his channel is doing quite a good job of giving a good ongoing overview of what is taking place.They really hate rob on the fishing forums. He's rich and can be a douche, but oh well.
Furthermore it's not like he's the ONLY place that I would ever look to for information. It's not like that at all, but rather so far his channel is a good source to keep tabs on the general idea of developments in 20 minutes or less (per day, sometimes twice a day). It's not bad at all.
Him being a rich douche bag with a nice bass boat has little bearing on his interpreting of loads of data on the Ukrainian conflict.
