Fair, I was not aware of that exception. It does seem to cover this case, assuming Google is actually not sending any data outside of the phone, use it for further training etc.

The person owning the phone where the processing takes place, is the processor of the data in this case. That still requires consent from the data subject per gdpr.
In many places call recording (or indeed processing of personal information which is highly likely to be present in phone calls) requires consent to be legal. I highly doubt this kind of processing is legal in the EU without both parties consenting.
S10e is great. It's what I've been using as well, but it doesn't get security updates anymore. Been using a custom rom which does get Android security updates, but there was a pretty serious SoC level security vulnerability which won't get fixed for the S10e.
I'll get a Pixel 8a instead. No headphone jack, slightly larger, only 1 physical sim. But can run GrapheneOS and have a long promised update period.
This is from 2023, but this might still be a good read on how to get to a very low watt idle build, there's a few more post on other older builds on that blog as well: https://mattgadient.com/7-watts-idle-on-intel-12th-13th-gen-the-foundation-for-building-a-low-power-server-nas/
None basically. There's a Sony phone has LineageOS (including +microg variant) support, but it's not ideal either.
The Linux Foundation has a mentorship programme which is really great, might be worth a look, although I am not sure how easy it is to get accepted: https://docs.linuxfoundation.org/lfx/mentorship/mentees
Music, dog.
If you are open to building something yourself this might be an alternative (disclaimer: I just know of this project but no idea how well it works): https://www.findmycat.io/
I've had success with this script https://gist.github.com/interfect/5f68381d55658d334e2bc4619d796476
You should be able to connect to the Chromecasts setup hotspot, get the IP of the Chromecast and then run the script.
The energy prices in Sweden were also mostly negative yesterday, and today as well. Although probably not quite as much as in Finland.
noyb has really done amazing work the last many years. They specialize especially in GDPR law and Schrems II (Max Schrems is the founder).
EDRi is another organisation doing a lot of good work in digital rights. They fight against chat control and such which is an area noyb is not so active.
These are the best EU based organisations to support imo. EFF does good work too, but a lot of that outside EU.
