Twitter has certainly done a loooot of harm, but to be fair it has done good as well. It wouldn't have grown like it did if people found no use for it.
You'd be hard pressed to name objectively positive things Twitter has done, which I imagine is why you didn't.
Astoundingly, you're not the first person to imply that there is literally no benefit to Twitter whatsoever, despite the awesome ease of finding the benefits by typing two or three words into DDG. That doesn't change the facts though.
Like, that's such a giant leap I struggle to even call it leap. If someone would give the perpetually drugged up guys in front of my local McDonald's a bunch of Semtex-H, I am sure they would find it quite useful, but I also doubt that the world will become a better place.
And, since apparently you need this spelled out, the reasons are quite dissimilar to the reasons "drugged up guys" would find explosives useful.
