I really don't know what's happening with this issue. Some people say some units are not affected. If that was true, some T2 chips would be defective and other T2 chips would be fine, and then, all units that were assembled in the last weeks would be fine, but we have reports from recent units having the issue. So, the reason isn't hardware, and the fact that some people suffer the issue and others not, shouldn't be because of hardware, but because of different software being used, different settings being enabled (FileVault, energy saving, sleep configuration, etc, etc, and combinations of these settings that can be set different across different users), and also because of the fact that some people use the computer in some ways, and others in another (some people are making the MBP sleep many times everyday, while others never make it sleep, or in very little occasions).
That's my feeling, because, otherwise, all new units should have fine T2 chips as of now. My guess is that all units have good hardware (I mean from this BridgeOS issue point of view only), and the problem is at MacOS, BridgeOS, and firmware. Some users hit it because of settings combinations, installed software, and their ways of using the MBP, and other users don't hit it.
