I'm not! I added the caveat to defense that not everyone thinks it has a positive influence, but the rest are hard to debate with. If you have reasons why they're negative, I'm open to hearing!
I think at least part of the objection would be to Palantir being on the list. They got into all kinds of hot water for helping Trump administration do various unethical things (I don't remember the specifics)
I listed them in the defense category as it's not universally viewed as positive (though I think it very much is sadly necessary and positive), but in addition to that, Palantir works with tons of positive organizations including the NCMEC (National Center for Missing & Exploited Children) on tracking and preventing child sex trafficking.
