The difference now is that there is no need for a Josef Goebbels. The vast majority of the legacy news media is already firmly vested furthering socialist propaganda.
Compounding the issue, those outlets that are on the opposite side of the political spectrum are firmly entrenched in their myopic worldview, too. And each or those echo chambers are firewalled against each other
Until other, independent news sources gain sufficient traction, the American public who actually pay attention to the news will be grossly misinformed of actual events. This only plays into the protesters/activists/insurrectionists agenda, where the truth is antithetical to their cause.
