Dude shroud got shit on for using it. No one cared. The only other pro I remember using something like that was magisk, using the sg krieg in some games. I heard that tonyblack used to buy it too, but that I cant confirm.
100%, people started using it after valve touched it, elige picked it up from day one and slowly it started to stick, karrigan picked up a bit later etc, but it was really at the start of this year that the aug took over
Still no kriegs, but if nothing changes they'll use it too. It's better as well.
