People have read this on turbohud site?:
Legal
“TurboHUD is not affiliated to Activision Blizzard and it may go against game TOS/EULA: [Blizzard Entertainment: Battle.net End User License Agreement]”
This is from mobalytics:
"Are Overlays, like Mobalytics, allowed for Diablo 4?
The Mobalytics Diablo IV overlay doesn’t provide the user with an advantage over others and doesn’t modify the game’s data in any way.
Read more from the Diablo IV support team here: Third Party App: Diablo IV overlay is permitted? #ModCheck - #4 by Overwolf-1116"
As much as i know, i know that turbo hud gives much more informations on the game/gameplay (that are not shown in the game, so it gives you an advantage) compared to mobalytics wich just give you times for the events, wich is why i guess people get banned
