Coupons, lies, and packet sniffers
Honey's Dieselgate: Detecting and Tricking Testers
Coupon plug‑in plays nice for testers, sneaks commissions for everyone else — and the comments are savage
TLDR: Investigators allege Honey’s coupon plug‑in behaves for testers but breaks rules for regular users to grab commissions. Commenters pile on with sarcasm, engineer‑ethics memes, and a veteran claiming sales didn’t suffer without affiliates, igniting a wider “who actually adds value?” debate that could shake coupon extensions and ad money
The internet’s favorite coupon helper just got hit with a “Dieselgate” vibe. YouTuber MegaLag and a researcher say Honey allegedly detects when it’s being watched by industry testers, behaves perfectly, then flips back to rule‑breaking for regular shoppers. Translation: affiliates and stores think they’re safe, while everyday users get the sneaky version. Commenters immediately brought the heat. One summed up the mood with “no honor among thieves,” while another asked the question haunting every coder: are we the baddies?
To non‑tech readers: affiliate marketing pays whoever’s link you clicked last. Critics say browser plug‑ins can jump in at the end and grab the cash. If Honey really plays by the rules only when it senses auditors, that’s the internet equivalent of cheating the exam and smiling for the principal. Users traded receipts and links, from MegaLag’s new video here to an archived deep dive here. There was even comic relief from someone who thought this was about literal honey fraud. The spiciest twist? A veteran says his company cut affiliate payouts and didn’t see sales drop, fueling a bigger debate: are coupon plug‑ins saving people money or just taking credit. Jokes, cynicism, and a faint chorus of “delete the extension?”—the comment section is on fire
