The author is a bit late to the party... People were complaining about Alcantera keyboard decks back in 2016 when it was first used on Surface devices. If the author has only just realised now it cannot have been too bad.

I had several Surface Pro units and am still using one. I keep themfor about 2 years each and the keyboards look new. Clean hands and a little maintenance does the trick. Looking at any keyboard with a microscope will alert you to the microscopic life on them but also on your table, countertop your bed, ect...

I fail to see the point here.
