Who has the God of this world not blinded?

The God of this world has not blinded the minds of those who haven't joined the church or don't read their Bible. He blinds the minds of those who believe not, that is, those who will not believe.

Les explains from II Corinthians 4:3-4 that the gospel is hid to them that are lost, and the God of this world has blinded the minds of them who believe not. Les clarifies this does not refer to people who haven't joined the church or don't read their Bible, but specifically to those who will not believe. The world outside is busy and lost, under the satanic powers, but the blinding is tied to unbelief, not church membership or Bible reading.

2 Corinthians 4:4

In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.

Who has blinded the minds of unbelievers in 2 Corinthians 4:4?

According to 2 Corinthians 4:4, the god of this world has blinded the minds of those who believe not. The context clarifies that this blinding is not for those who merely fail to join a church or read the Bible, but for those who will not believe.
