So far their main argument was that he desired to fuck 5000 women. What man doesn't desire that?
Well, a smart man, a man with a target on his back, knows this type of behavior is a bad idea. I forget who it was, someone famous, said he doesn't even get into an elevator alone with a strange woman, too risky. If I had the opportunity I wouldn't actually want to fuck hundreds of women, let alone 5000 LOL, a few would do

Russell is one of the most influential people in the country and his views dont align with the rulers.
He will become too powerful if they don’t try to take him down now.
I don't know much about Brand but I got curious, has he been accused of being a Russian asset, so I googled. Sure enough, he has. However, when getting conspiratorial you also have to consider that he may be controlled opposition LOL. Case in point: Tucker Carlson has been accused of being a Russian asset. Or he's a Qatari asset, he's Tucker Qatarlson. But, many conspiracy theorists think Tucker is actually a CIA operation haha. Tucker's father was CIA so Tucker is CIA as well, he's controlled opposition. He wouldn't have this platform if he was really a Russian asset, or if he was really, actually, antisemitic, he would have had an accident.
You're going to ask these questions if you go down the rabbit hole

I do believe intelligence operations are a real thing in the social media world. Sometimes assets are taken down when they have served their purpose or become inconvenient. Some people are assets without even knowing it, that happens too, they may be influenced, their ideas may be shaped by assets, without knowing their friends are assets

I haven't checked it out yet, but I heard mention of a new Netflix movie or "documentary" about the Unabomber. The premise is that he volunteered to take part in some psychological experiment at University I think. He didn't know it was a CIA operation; the purpose was to find out what it took to break down a man. I haven't even gotten around to reading his manifesto in full but many say it's very "intelligent." I even printed it out to some coworker while at work LOL.
