Have you ever used one?
You are doing it to a just washed car, there should be no loose debris that can get picked up and scratch the paint.
Towels, microfibers, and traditional chamois are worse at holding onto particulate debris, if that is the concern.
I first saw them at a high-end auto painter, that guy swore by them and I doubt he is a fan of ruining his own work.
Because if even one single piece of sand, dirt, gravel, etc gets caught under that blade you drag it ALL the way across the paint.
The point of drying (blotting, not rubbing) with microfiber is that if, god forbid, there is a piece of sand, the pile of the MF picks it up and buries it in the pile before it can do any damage.
Chamois and 'The Absorber' synthetic chamois would have the same problem as a 'water blade' except you're not dragging them across the surface so the possibility of damage is minimal.
Fell free to use it yourself. I'm not trying to stop you. I'm just explaining what could possibly
happen in case people are weighing the pros and cons of each way for themselves.
