When I got home, I saw a large white ring, a telltale indication
that the HomePod’s silicone base had messed up the finish. But, as
I was inspecting the damage, I noticed a series of smaller white
marks near where the HomePod was sitting.
A closer inspection revealed that the Sonos One speaker, which
also has small silicone feet, had made these marks on my cabinet.
Looking around the top of the cabinet, I noticed a bunch of little
white marks, all left from the Sonos Ones as I moved them around.
So, they will damage your wood furniture, too.
