After reading about the situation with mobile phones and free software,
I've come to the conclusion that they are trackers. How can I live without
a mobile phone then? Is it inconvenient?
Perhaps it is inconvenient but privacy is more important. I'm sure there
are lots of people who live full and complete lives without being tracked
or handling phone calls everywhere they go.
I like using bluetooth earphones or headphones on the go. I am thinking of
carrying a computer folded in a backpack, running free software and
supplying me with audio via bluetooth. Is there an obvious reason why this
would not work?
If you want to listen to audio you can find small unnetworked digital audio
players that will fit in your pocket and work with wired headphones. This
approach will let you avoid broadcasting your audio via Bluetooth. Check
out the https://www.rockbox.org/ firmware (licensed under the GNU GPL v2 or
later) for supported devices. Perhaps there is an inexpensive used digital
audio player you can upgrade with Rockbox so you can pay less, get
something Rockbox supports, and avoid paying the manufacturer while gaining
the practical benefits of that device.
