Can you provide some reasons other than a seemingly random statement like "run a random executable on my personal computer", that apparently is based on some specific certain personal perception? I'd call Skype anything but random ... at least in comparison with Hangouts. What is your point?

Also you might want to change your title. You talk about not joining meetings with propriety software, then mention Hangouts is okay, which - as you even mention by yourself - is proprietary software.

tl;dr your post is really confusing and I am not sure what you are trying to tell.
