Yes but, it incudes defaults from Alphabet. And this software is designed to extract as many data as possible. Even if you use it without gapps, it ping too google every time your WLAN Application check if a new connected Hotspot or Mobil-Data Link, have Online capacity to reach the internet, by ping a google Server. So they have your IP in the Logs. And every Push-Message will transmitted through the google system too.
And i think, -but this one is not proofed or backuped by research i know about- they use the BLE Pings used by Covid-Tracing-Apps, to measure movement and meetings between Devices. I am not sure, but i think they do it already to measure every WLAN and near BLE Devices, like Airtags and transmit that Data too, as Telemetry or just as, you only can use our software if you let us use your device to survey the world around you in realtime.
Here is a link of a german Researcher, who looked at LineageOS:
Its only in German but feel free to translate it with DeepL (or a Dictionary - just kidding)
I think this was not fair, cause the Lineage-Folks and the Android Community on free Roms Spent Time to accomplish a working Image of actual Code, with Patches. So Lineageos have the pros an cons like every free software has. It need more care and understanding. However using it in the wrong way will teach users to understand. Instead of Microsoft in the 1990 and instead of a small aspect of focus on own needs by a small complexity of software (whatever it implies in our world today and with its million lines of unread code), it did not compete with the search of guilt, from the poison tree with the Surveillance Capitalism focus. That its more important to spread software and expose users behavior and offer future modification to third (partie)s or in AI interests.
I am not sure if we can compete with that… had a dream today about what if the next level of humanity was after they upload Minds to Computers and gain immortality - then everyone who do not deliver to that Computer System missed the Backup…(?!) and i was not at the Party.
Just a Joke. This is less probable than my/our descendants will survive in a physical world.
However, in the end it will be a hard competition for us, to spread good (whatever the definition is), free Software and Devices to our surviving mankind.
I can not see in the future, but like a muscle you do not train/use, you will lost abilities to Computers if you do not need them. And i think pushing complex Smartphones with High speed Internet Connections, is no good idea or gift for your child, if the device itself use filters and behavior changing/learning (optimizing spend time) algorithms which tune behavior for the next Dopamin boost.
I know right now my focus is too conservative and i lean towards a pessimistic sight, but the time has spread that story too long. Hope it will begin a new change with some Linux Phone. Because our possibilities grow with that device.
