When you're making a word processor you can be nonpolitical pretty easily, Microsoft doesn't get any heat about what users of Microsoft Word are doing with it. Child abusers and the KKK use Excel? Everyone knows Microsoft are just selling hammers.
When you're making a 'platform' website, on your domain with your ads and your branding and your anti-spam policies? Even if the stuff people disagree with is 'user-generated' it won't stop powerful people asking if you're doing enough, and employees asking you to stop doing business with ICE.
Making a computer program that will write an essay about the causes of the civil war? A computer program you can hand a document about Thomas Jefferson's politics, and ask it to summarise the most important points? Or that you can ask for medical advice during a pandemic? Oh, and it's also going to take a bunch of people's jobs? Ooooh boy, I hope Sam Altman likes testifying in front of congress.
