Google announced a significant update to Chrome on Android, incorporating on-device machine learning to identify and categorize potential spam in web push notifications, which may lead to users opting out more frequently. This change has sparked debate among developers, with some seeing it as a positive move to reduce unwanted notifications and others concerned about its impact on communication channels that require user permission. Despite web push notifications being an open channel, they are increasingly deprioritized, similar to past challenges faced with other platforms like Safari. Developers are advised to maintain good domain hygiene and carefully audit notification content to avoid spam flags. The update is currently limited to Chrome on Android, but it could expand, prompting developers to explore solutions like Knock, a platform that enhances notification quality to mitigate spam detection risks.
