OpenCandy

OpenCandy measured early traction through installation metrics—millions of bundled downloads across partner software installers showed users weren't actively rejecting the prompts. ​​‌‌‌‌‌‌‌​‌‌​​‌​​​​​​‌‌​‌‌‌​​​‌‌SweetLabs interpreted low opt-out rates as validation, believing the behavioral signal of clicking "next" during installation proved genuine interest in their recommendations. They measured engagement by tracking how many users accepted suggested software installations, seeing 15-20% conversion rates as evidence of real demand. However, OpenCandy conflated passive acceptance with active desire. Users installing legitimate software weren't consciously choosing OpenCandy; they were navigating installation wizards where recommendations appeared as defaults. The critical warning sign was that demand evaporated instantly when friction increased—users actively uninstalled the software and complained loudly once they understood what it did. The gap between stated interest (implied consent) and revealed preference (actual usage and satisfaction) proved fatal. OpenCandy had measured willingness to click through, not willingness to pay or genuine product love. When antivirus vendors began flagging it as malware, the business collapsed because it lacked authentic user demand—only distribution leverage.
