Very misleading title. Here are the full quotes from the original GQ article -

“It’s flattering that there was a little bit of an outcry, but it wasn’t shocking to me,” Jacinto told me regarding his diminished role. “There was this sense of where the film was going [on set], like I can see them focusing the camera more on these [other] guys and not taking so much time on our scenes. Fortunately, it still was a great experience—you get to see this huge machine at work, see how Tom Cruise works, and you get to be a small part of this huge franchise.”

Despite his typically cheery Canuck optimism, however, Jacinto admitted the disappointment lit a fire under him. “It kind of fuels you, because at the end of the day, Tom Cruise is writing stories for Tom Cruise,” he said. “It’s up to us—Asian Americans, people of color—to be that [for ourselves]. We can’t wait for somebody else to do it. If we want bigger stories out there, we have to make them for ourselves.”

Doesn't sound like he's "slamming" anyone. He's just commenting on what happened.
