You can find many references by googling some variations of keywords Docker, Windows, brick

Googled that, thanks for not providing clear references to your claims, and found that docker can crash Windows on boot, but not "brick" it. People are still able to safe boot, run system recovery/restore, or even reinstall Windows if they choose.

Besides, bricking software is impossible, bricking refers to physical devices unable to bootstrap anymore.

Not exactly. Hard brick is what you are referring to where you need to repair/reset the hardware OEM after corruption.

A soft brick is the actual reference here where you can easily recover from software/re-install.
