How did the Sedition Act expand the powers of the federal government in 1798?

It allowed the Federal government to limit free speech during times of war. An example is if the United States was currently in war and you outwardly said in public ”the war is meaningless, our government is not supporting freedom, the military is making our soldiers fight for oil companies don't join!”. The government may arrest you because you outwardly spoke out against it in times of war.
