I think 1 and 2 are more the issue, but possibly all of them. They are all loose definitions that mean different things to different people. I think it would limit serious uptake once a legal department gets a hold of it.

(1) discriminating against marginalized communities

What does this mean? I bet I could get several different answers. Old people are marginalized by agism in tech, does this mean tech companies can't use this? How would they prove they don't marginalize old people?

(2) building tools that disingenuously manipulate public opinion

Ditto. To me this means no political party or marketing/advertising department can use this. Probably most news outlets as well.

(3) building tools of mass surveillance and prediction to repress the rights of people

Rights defined by whom? US Constitution? Right not to be offended? Rights granted by the Taliban or ISIS? Communist China?

(4) building tools that control weapons, including tools that automate the deployment, operation, and targeting of weapons.

I think most people can get on board with this one, unless we were attacked in earnest by a strong military foe.
