Users are now getting Android's convoluted sideloading process, and everyone hates it
(www.androidauthority.com)
once you’ve waited 24 hours, you can choose to allow sideloading for seven days or indefinitely.
I know I'm going against the current here, but I don't think this is a bad change at all. It's a step to protect normies from themselves who, despite how inconceivable it is to fall for this kind of scam, are actually even dumber than that.
I do think it's reasonable to be worried about future changes that further restrict sideloading. It's often how these restrictions are slowly implemented. But where it's at now with this change in particular I'm cool with.
