A misleading article claiming big privacy breaches, while testing only one Qualcomm phone, that too is old (legacy device). On my de-googled xiaomi phone with sd888, i can't find any connections to izatcloud.net. Besides, AOSP doesn't connect to android.clients.google.com for Android device registration, microG does. You used e/OS with microG bundled in, but didn't used vanilla LineageOS or GrapheneOS which ships without microG. Remember, microG is an implementation of Play Services. Therefore, i find this article a clickbait, which causes FUD amongst privacy-focused people.
