> Deliberate design choices are what made fake news effective.

These choices are made by whoever makes the fake news site. They are (ab)users of technology and not its creators. It's like saying encyclopedias are evil because you can take a heavy tome of encyclopedia and hit somebody in the head with it.

I am not saying solving fake news problem (if it exists) would be a bad thing. I am saying just like email is not evil because spammers exist, no technology is evil because fake news exist.
