Android 14 blocks all modification of system certificates, even as root

I learned that Android was not open under my personal definition of "open" right from the outset, because there was no programmatic access to telephony. My first project was to build an on-board answering machine with call screening capabilities.

I used an answering machine on my landline to avoid paying for caller id and voicemail and wanted to do the same with my cellphone. I was very disappointed to learn that this was not possible, at least with my skillset.

I knew that things were going the wrong way when my Tasker script to manage airplane mode stopped working when Android required locked it away. My use case there was that lack of connectivity at the gym and at home meant that connection attempts were draining my battery and heating up the phone. Now, of course, Android does a much better job of that particular task on its own, but it still makes me cranky. :)

Everything that has happened since has only cemented my opinion that Android is not actually an open platform. I do see many of the changes as potentially valuable security measures for the masses, but I wish that it wasn't quite so difficult for a power user to use the power of the little computer we carry in our pockets.
