You act like there won't be any devices at all?
There'd still be TVs, radios, newspapers, etc.
These movements don't NEED the internet. The internet just helps those movements. But it doesn't take away the fact that the internet has still done more bad on average than it has good.
Think of all the people who've been harassed by racists, or creeps, or misogynists, or more. And some people even get pushed to suicide because of that.
There's also a ton of gore, child pornography, and more all over the internet. Especially on sites like Twitter.
I gotta say, I really don't think the internet was a good idea. At the very most it should have stayed the way it was over a decade ago
