This is mostly nonsense of course and you are assuming everyone has the same connection and hardware problem and that is why any user should start with diagnosing their debug logs which is far easier than taking apart the My Cloud Home and forgoing the remaining warranty, if any.
Looking through your posts and thread, it is mostly rants about poor support without much documentation and you never posted anything about the age and usage hours of your My Cloud Home, the debug logs such as the kernel logs, the sataa health check and SMART diagnosis. For all we know, there could have been too many hardware errors which would have prevented the normal OTA firmware from WD server from updating which is one of the reason why some units lose connection when their firmware failed to update. There are many well documented posts such as this below and explanations in the forum, just look for it
