I've been playing CS since even before 1.6 and I don't mind the scope meta at all, I honestly feel like CS has moved way beyond ScreaM's kind of flicks. It needs to move on the direction that Astralis is pushing it, where smart CS beats raw skill.
Scoped guns add new variables to the game, you shouldn't nerf those but instead change the way you play with them. Like make that the AUG noticeably slow you down but without all the current nerfs, that the SG pattern go wild after the first 3 bullets if you aren't scoped. Make them non-expensive viable guns, but force the players to put some thought behind going for the scoped guns or not. The game will only gain in depth if there's more good options to play with, just don't make guns better or worse, make them different.
