The only solution is to fight it and kill it.

That's like saying the only way to get out of being hit by flying debris is to eliminate all wind on the planet. As much as we like to think of Threads as some corporate being, it's not. It's a hundred million people that are made of meat and have day jobs like you and me - the wind - and a few million bots and controlled accounts which attempt to influence [whatever their master wishes] - the debris. The debris is already here, and it's people too - just people with nefarious or profiteering intent. It (debris) happens whenever there are enough people (enough wind) to stir things up.

Cutting yourself off from people is the only way to prevent it because it's an inherent function of humanity.
