Why? You just need to choose electronics that doesn't use micro mechanical designs that would be damaged by helium. (Or are you pointing at some other reason?)
One possible reason (not the GP so I don't know if this is theirs) is that there's a finite amount of helium available, so using it for this sort of use case depletes it for others.
Personally I think a hydrogen version would be hilarious but others might disagree...
I was about to argue that surely the consumption of helium in balloons must be tiny compared to industrial use, but apparently it makes up 5-10% of all helium consumption? That is a magnitude more than I thought, and certainly nothing to ignore for a finite and irreplaceable resource that we need for stuff like MRI machines.
