Talking to the wrong guy here, I've taken many a medications against their intended purpose: I am a curious guy.

But that sounds like saying, in the context of Google's intention of disabling app sideloading, that warning users that it poses a security risk because it's their intended purpose for android, is fine because the authority on android is Google.

Don't just take the word of authority at face value, when they prioritize profit and mindshare over personal freedom.

You are the master of your body, the person who decides ultimately what goes in and out of your body, No doctor can force you to take anything. That's what I mean, The play store aka the doctor wants to become the master that decides what apps go in or out of your phone, instead of the user. My comment doesn't invalidate the premise of the use of the term sideloading, because I don't agree with the term to begin with.

Whether the effect is ideal or not does not change what is chemically happening in the body. The body can't tell apart side effects from the main ones, so this distinction exists because humans deemed it so, just like the distinction between play store sanctioned apps, and everything else. It's a distinction that Google is now abusing for it's own monetary benefit.

It's a bad comparison because some people do take the medicine to get the side effects. For example taking benadryl to fall asleep.
