As foobarbazetc noted, the listed packages have been specifically developed for Nokia (HMD). And although many only actually send telemetry on Nokia phones that have been sold in China, there is still quite a lot of data at stake that can be used to track the device when combined with data from other sources. I wanted to share my findings to create the awareness that the mechanisms are there and it only takes a little misconfiguration (see https://arstechnica.com/gadgets/2019/03/hmd-admits-the-nokia-7-plus-was-sending-personal-data-to-china https://arstechnica.com/gadgets/2019/03/hmd-admits-the-nokia...) and all this goes straight to the Chinese authorities.
