Allow me to disagree. Am well involved in making those technologies and well aware of the internals of cell networks. This is not what Android does, during the recent updates it has strengthened the ability to detect cell spoofing etc. Your phone literally will tell you that there is a fake cell tower around. Have you disabled 2G fallback? I guess no, good guy Google did it for you.

Cell tech aside, your actions, even remarkable based on the average person, leave quite a lot to the advertisers.

Have you spoofed the imu of your device? Or the brightness? Or maybe you visit websites asynchronously? Or maybe your IoT devices are isolated? And your smart tv is on an isolated vlan? Or is your phone location spoofed while you have a vpn enabled? Same for Bluetooth background scanning? Are you sure your neighbor’s WiFis do not retransmit your mac? And your car is always offline? And your modem/router does not have isp admin account? How about your imei, spoofed? Do you authenticate to your wifi using radius? Background phone processes are always killed and no auto-started on boot or other events? Want to discuss maybe your neighborhood cameras and if they include you and your car? How about webgl and canvas in your browser, disabled? Which DNS are you using while on vpn? How do you protect yourself from CDN fingerprinting? Have you checked your browser fingerprint? Do you know how easy it is to be identified if you only have reduced privacy in 3 of those?

Privacy is a joke in 2025.

Is this based on some knowledge or evidence?

That’s not correct at all. Did you visit lenovo.com lately?

This is no news. Lenovo has been offering a variety of windows or no OS for years.
