I was glad to hear your podcast about being a more conscientious free software user.  I was very impressed to hear you started out alone, without peers to talk to and help.

Have you heard of vrms?  It's a debian package (maybe available on other platforms) - "virtual RMS" - it checks what you have installed on your machine and sends you a monthly email with a list of non-free software.  So it could help with your goal of moving more towards the free software ideal.

I'm not all they way there myself, but I'm always trying to be more free.

Re: the tracking/EULA/DMA stuff, for your Android software you can use the fdroid repo instead of google play.  It is all open source packages, and the installer will let you see the required permissions before you install.  So even though it is all "open source" it is not all desirable and you do want to check the required permissions before you install.

I find I am limited in what I can install on my phone, but like you, I have a bit of patience.
