This is a bad faith post intentionally spreading misinformation.
Ignoring the quality of these studies, the first concluded that cloth masks were less effective than medical masks, not that the are worse than no mask. It also evaluated and discussed the use of cloth masks to protect health care workers, not to slow the spread of sars-cov-2 via respiratory droplets.
The second, tiny, study says nothing about damage. Their results suggested that surgical masks reduce cardiopulmonary function slightly with surgical masks and a little more with N95 masks.
I'm glad both exist for sure. My favorite thing about the chip is lipo charging built-in. But micro-sd, HDMI, and the camera connector on the Pi are useful too.
