The Infernal Revolting Syndicate's sole objective is extortion and terror.

And this letter fulfils both.

If they were truly about taxing cryptos, they would have firmly defined what a crypto-coin is and what a crypto-token is.
And then laid out definitive terms and examples of what is taxable.

Instead, they are playing both sides of the fence. Choosing whichever suits them best in the moment.

This is what they do. Terrorize people.
