Owner Elon Musk has supported Trump's election campaign in various unethical ways.

The 5 main issues with Grok

Big Tech - Big Tech companies do not nourish people and planet. This is especially true in times of political tension.

xAI is backed by major tech figures, contributing to market monopolisation.

Privacy Concerns - User data is likely to be stored and used against users' best interest.

Grok has significant privacy concerns, especially because it mines user data from X. Source:Wired: What You Need to Know About Grok AI and Your Privacy (2024)

Misinformation / Manipulation - Spread of false or misleading information, often through algorithmic amplification, which can harm public discourse and trust.

Missing guardrails in Grok's design lead to outrageous output and increases vulnerability to fake news and propaganda. Grok notoriously referred to itself as "MechaHitler" after spewing antisemitic, racist slurs. On X, Grok has "nudified" millions of images without the consent of the victims. Grok is owned by Elon Musk, who is known for his reckless manipulation of software to spread propaganda.

No Carbon Neutrality Goals - No goals for carbon neutrality is a bad sign as it shows lack of commitment to holding crucial thresholds for global climate warming.

xAI does not publish any goals towards carbon neutrality. Its data centres draw backlashes from local communities for polluting the air with uncontrolled emissions.Source: Politico: 'How come I can’t breathe?': Musk's data company draws a backlash in Memphis (2025)

Support of Authoritarian Regimes - Companies actively supporting, financing and legitimising regimes and unethical policies.

Elon Musk has supported Trump's election in 2024 by publicly endorsing him, financing the campaign and amplifying misinformation on Twitter/X and Grok.Source:Wired: This Was the Year Elon Musk Took Over Politics (2024)
