Another demonstration that duct tape can fix almost everything. Put a little over the webcam and presto, no more malware spying on you through webcam video. Now about something for the microphone?
And arguably if one applies duct tape all over the laptop, the laptop can no longer be used, therefore no data can be input into it, preventing that data to be then exfiltrated by malware. A truly versatile product.
It’s easy enough to disassemble your thinkpad and unplug the mike. Use external mikes if you need them, they will be better quality anyways
