Yeah in fact I don't really see what's new in this article except that it hints that it will allow install of software from unverified developers via big scary warnings. Which seems like an improvement from what has been announced previously that only software from verified developers would be allowed.

I already have to configure apps to allow them to install apps on my Pixel... it's like "okay yeah I want to allow F-Droid and Obtainium to install apps" done. Maybe that's not the default or something? Who on earth wants popup ads in Chrome installing shit? And why would anyone want any random app to be able to install additional apps?
