It tickles me when I read of journalists protecting their privacy. You can see how far up the tree they’ve climbed.
There are many, many more ways to track that anonymous phone. These are feel-good settings to disable for that sense of false security; like you’re in control. It does have effect, don’t get me wrong.
But a big part of tracking is not what your phone sends, but other devices detect. There’s no opt out of that data collection.
I do that too, but had to add another variable. I use a priority-level or yearly rotating trigger word to pick out messages from spam. Keeps more of the riffraff out and easy to ban old temp addresses.
