Both Perimeno and Robert King have similar viewpoints. They're good steppingstones for people who just can't come to grips with the fact that they've been living a complete lie as JWs. It lets us feel like we've been living only partial lies and that the WT, while deeply flawed, is as wobble says, "an organization that Almighty God has some kind of interest in or contact with."
That said, I also think there are some prophetic insights to be gained from reading their materials. Where the WT applies God's judgments to Christendom and the rest of "the world empire of false religion" and Perimeno and King apply those judgments primarily to the WT org, holding both views up to the light and looking through them gives me the perspective that God is going to judge every organization on earth and that those who claim to be his people (which is pretty much every organized religious faith) will come under especial scrutiny.
So there's value there if one still believes in God and the Bible and an imminent modern day fulfillment of prophecies. Just don't take them as gospel any more than anything else on the Internet.
