Black Ops 7's wallhack killstreak is receiving a frenzy of criticism, but isn't the point of killstreaks that they're unfair?

A clip from today's Call of Duty: Black Ops 7 event has gone mildly viral, and is attracting the ire of onlookers who seem to feel that Call of Duty has, this time, gone too far with the wacky gadgets and guns.

The clip (embedded above) shows Call of Duty pro Simp using one of Blops 7's new killstreak rewards, The Gravemaker, a sniper rifle whose wielder can see, and snipe, through solid walls. The go-to joke is that Activision has given up on combating cheaters and decided to just put wallhacking into the game.

I sort of get the indignation, because it doesn't look fun to be on the receiving end of a bullet that was fired through two layers of concrete by someone you never could've seen, but I also sort of don't get it, because aren't all Call of Duty killstreaks like that?

How is this
