Interesting I always thought it was true! Do you mind providing a source?

If you have two atoms in quantum entanglement, and you change the spin of one atom, the other atom will change it's spin to be opposite. Isn't this the essence of transmitting information?

So far as we know, nothing can travel faster than the speed of light. However, a relatively new discovery/concept is called "Quantum Entanglement" in which two or more particles can become connected seemingly regardless of the space between them. In such a case, information could theoretically be transmitted instantaneously
