PayPal-owned browser extension Honey manipulates affiliate marketing systems and withholds discount information from users, according to an investigation by YouTube channel MegaLag.

The extension — which rose in popularity after promising it consumers it would find them the best online deals — replaces existing affiliate cookies with its own during checkout, diverting commission payments from content creators who promoted the products to PayPal, MegaLag reported in a 23-minute video [YouTube link].

The investigation revealed that Honey, which PayPal acquired in 2019 for $4 billion, allows merchants in its cashback program to control which coupons appear to users, hiding better publicly available discounts.
