I try really hard not to be biased towards my teams regarding officiating. I watched this in slow motion a bunch of times, and I was about to agree with the refs on this. The initial contact is with the ball and parts of Hawkins' hand that are touching the ball, which is legal. There's some subsequent contact with parts of Hawkins' hand that are not touching the ball after Edey's hand swipes across the ball, but that's typically allowed if not severe. There was no interference or goaltending (he didn't hit the rim in a way that it caused the ball to move since the ball never even touches the rim, and he is allowed to continue touching the ball when it enters the cylinder).
But Edey fouled Hawkins with tricep-to-head contact. Was it minimal (or something they were allowing throughout the game) and probably not what the officials were focusing on? Maybe. So I'll say this was an "incorrect" call rather than "bad" or "egregious".
That said, Hawkins needed to create more space with his body in order to make any fouls more obvious and/or prevent the block entirely.
IMO the "hand is touching ball so feel free to slap the !!!! out of it" rule makes no sense.
