Sorry but I got to disagree with you because it was reviewed, not only 1 ref made a decision, it was a unanimous one and I think they know their job better, unless we think it was rigged.
Look at the screen below:

So call it what you will. But watching it live like I did, you can see where the ball's trajectory was going and where he grabbed the ball to dunk it for the score.
Allow me to joined the discussion here. I also checked some video regarding that controvertial call by the refs, as you can see in

And here's some of the comment that agreed with the call.
And this one could explain as well.
What is basket interference? Explaining controversial call on Karl-Anthony Towns in Timberwolves' loss to Mavericks
Touch any ball from within the playing area when it is above the basket ring and within the imaginary cylinder.
Offensive goaltending is rarely called. The shot Wednesday appeared to be leaving area of the rim, though it could have had a chance to hit the rim again on the way down, making it a close call for the referees.
So it was a close call, and since refs made the final decision, we just have to accept it and move on, besides, this is just game 1.
