I agree with your point about "install" vs "sideload".

> Google’s message that “Sideloading is Not Going Away” is clear, concise, and false

Given your(and my) definition, this statement is false. Google isn't taking away sideloading, you can still use adb. I'd say using adb to load an apk from another device is the proper use of "sideloading".

What Google is doing is much worse, they are taking away your ability to _install_ software.

And yes, HN loves splitting hairs. But if it wasn't for the hairsplitting, there probably would be be much discussion. Just most people agreeing with you and a few folks who would prefer to give up freedom for security.
