I got into them right before The Odyssey dropped, so I too kind of fell into the "angry" Russ vibe first, but let's be real - it's a fucking insane criticism from "fans" of the band. Symphony X was never Yes or Porcupine Tree. They always played metal, always relied on being very very heavy. He's not doing screaming vocals any more than Dio or David Lee Roth would during their heaviest stuff. It's not some huge colossal change in the band's sound. People need to untuck their King Crimson shirts from their belts and get a grip.
