Absurd headline. Gizmodo's anti-tech bias is showing pretty clearly here. This makes total sense as a product strategy. Not sure what's so controversial about giving more reach to Threads posts as this already works pretty well for Instagram stories
That said. Facebook and instagram are both already a lost cause in this regard.
Perhaps what the article meant by the carousel has lead to an "insufferable experience" - is that its annoyingly addictive. In my experience as a passive consumer - I do find I pop open the FB app and then somehow get sucked into the reels... which as a user is annoying but probably highly lucrative for Meta.
My take is that this is the secret sauce of Meta - whereas any new social app needs to grow views organically - Meta uniquely can jumpstart a new social app through its ability to drive view counts through carousels on its existing properties.
