@witch_t *navi I don't say "sideloading" in the context of phones either. Just say "installing".
I have never had an Android phone with Google Play on it in my life. Installing APKs or using F-Droid were always the normal way of installing things on my phone.
"sideloading" is a term that makes it sound like a thing that is not normal, or something only "power users" should be able to do.
I prefer to see the headline:
"Google is preventing users from installing software"
vs.
"Google is preventing users from sideloading"
One sounds a lot more serious.
