Essentially, the gist of the complaint is that Soros is the world's largest social engineer. This is obviously very relevant in the context of Soros calling for tech firms to be tightly controlled so people only see "right" information, as he sees it - this would seem likely to be another part of his social engineering effort.
He has set up a fund with about 32 billion dollars in it, explicitly for the purpose of ensuring society follows his preferred path - one world government, open borders everywhere, EU replacing national governments, legal abortion everywhere, mass migration from Africa and so on.
To achieve this Soros must have tremendous influence on politics, which he does through his extensive lobbying, and his fund - being dedicated specifically to the global triumph of liberal politics - routinely makes huge donations to political parties, campaign groups, etc around the world.

Thus an article where he calls for important news feeds to be controlled by governments is concerning for two reasons:
1. It's not just a guy with an opinion. It is a public instruction to all politicians everywhere on what they must do to qualify for more of his money.
2. He is likely being disingenuous about his real reasons. He says "think of the children" but his foundation is not about child protection. It puts far more emphasis on migration policies than that.
