Business owners carry a lot more stress than salaried employees (generalization but directionally true). They also don't have a "boss" that can fire them. Those two things are likely the reason for a higher likelihood of bad behavior.
I don't think there has ever been a company so poorly understood (willfully or otherwise) as Palantir. They make a software platform, it does not come with any data, does not come connected to any datasources, etc. You can literally sign up right now for a trial and see this for yourself. It looks the same if you were to purchase a license. This headline might as well say 'Say No to PostgreSQL' or 'Say No to Excel' or 'Say No to Salesforce', etc. Wild.
