A YouTuber is suing PayPal after its Honey browser extension was recently caught tricking customers and snatching creators’ affiliate revenue.

A new lawsuit alleges that the PayPal-owned browser extension Honey is cheating creators out of money. Honey, which PayPal acquired for $4 billion in 2019, works by automatically presenting users with relevant coupon codes as they shop.

A video tech investigator detailed evidence and claims Honey systematically steals referral commissions from influencers—including those it pays to promote the app.
