Communication is key and we have none right now. How long before someone tells us what is really happening here? I am worried for the future of the game on those platforms. Will we always get everything late? Because if so, maybe you should advertise it as such.
Well, Google might very well pull plug on Stadia before BG3 is released, so I would certainly be worried for the Stadia version, but not really because of anything related to Larian. I wouldn't be worried for the Mac versions, they're probably just PITA (or at least additional work - Apple's very special™ proprietary APIs and also their new CPUs/GPUs being relatively new) to implement.
