David Marcus publicly criticizes PayPal’s updated Acceptable Use Policy (AUP), framing it as allowing PayPal to seize user funds based on speech-related disagreement. This is a reputational/regulatory narrative risk event that could pressure PYPL sentiment, increase churn risk, and benefit payment competitors if the controversy gains traction.
