Youtube Channel MegaLag did a good video breaking down malicious ways that the Honey extension works and the misleading claims that the company and partner youtube channels have been making regarding it, as well as how the business itself harms those same channels.
Here is the video;
And here is a tl;dw of the key points. I'd recommend the video for proof and more in depth explanation:
1. Honey replaces any affiliate links with their own
2. Honey inserts their affiliate links when the extension is used, even if it doesn't "find" any deals
3. Honey doesn't actually find you the best deals
4. Honey allows businesses to restrict what deals honey provides and advertises it to be a feature to prevent consumers from getting discounts that are too high
There is a part two of the video coming soon which looks like it'll be tackling the times it does have fantastic discounts, that it shouldn't have (ie internal employee discounts etc)
I've never personally used it but I know people who have, so this is interesting and more of a PSA than anything.
Have you used Honey or any similar extensions?
