> Assuming no personal identifyable information is saved, this is legal. This is not true in Europe Anymore. Any Optout telemetry is illegal because they have to establish a connection to the telemetry server and thus leaking the user IP (which is PII for GDPR) without the user's consent. See the latest case that even linking a font from CDNs is illegal. https://rewis.io/urteile/urteil/lhm-20-01-2022-3-o-1749320/ https://rewis.io/urteile/urteil/lhm-20-01-2022-3-o-1749320/ relevant part: > It is sufficient that the defendant has the abstract possibility of identifying the persons behind the IP address. Whether the defendant or X. has the specific opportunity to link the IP address to the plaintiff is irrelevant. Any connection that is not neccessary for the primary purpose of the tool/app needs to have the consent of the user thus all opt-out telemetry is illegal because the tool/app can execute its purpose just fine without the telemetry Note that this is not a problem only of the toolmaker, this is a problem also for the employers that are exposing the developers to these tools creating unneccesary burdons for them to gather the consent of their employees.
