tl;dr Because developer neither wasted time on Android apps nor learnt how to code properly, these kind of blog pops up. There's absolutely no random action when user presses a button, it's clear to person of intelligence level of 5 year old. Maybe author lacks that.

First, it only shows the apps that can share images/video, and also remembers the most used share so that user don't have to click to see share pop-up at all.
