No.
Nerfing moving would be hugely detrimental to the game. The game already heavily favors lame camping play styles, it's full of window campers and people who would rather play as a turret because the trash visibility makes it so easy to hide and accuracy is given bonuses for being stationary. For every one player with movement skill there's ten who will spend most of the match prone in a corner or camping through a window.
If you lose to someone who jump-slides your corner camp then you were flat outplayed. Corner camping already has the advantage of camouflage, pre-ADS, and stationary accuracy bonuses. If you die to someone with movement with all those advantages then it's 100% a skill issue.
