Yes, it sure looks like they are trying to silence the witness and the warnings.

Also, you are correct that now is the time to warn.

Most of us are far too afraid to tell people about fire and brimstone, or worse yet, what if some of us don't really believe that part?

As if we think we can pick or choose what parts we believe.

At least the LORD will supersede big tech, and not even need the internet or electricity:

Revelation 14:6 And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,

Then, the passage that you referred to:

Revelation 14:9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,

  10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:

  11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.

The people of the earth hear the warning in their own tongue, similar to Acts 2.

No one will have an excuse at that point, apparently the whole world will hear the warning.

But, I agree with you, it is our duty to warn people.

Even in the church age, before the tribulation, if someone dies, and they never repented and believed on Jesus,

they will have the exact same damnation of the lake of fire, that the worshippers of the beast in the tribulation will have.

It is very telling that so often fire and brimstone is left out of the gospel witness, and so is repentance left out.

Why do you think that is?
