Sorry, I had just woken up so I missed it 😓. I would suggest asking this in your distro’s forum if you still have Linux installed on that laptop.

What GPU does your laptop have?

What phone model is it? You can probably unlock the bootloader and install a de-googled rom, or get root access and de-google it yourself.

How is “lüften” a weird cultish ritual? I’m not German, but opening your windows in the morning and in the evening while doing things like brushing your teeth or showering seems pretty standard to me.
