Why do you have so much interest in a company you don't hold, apart from the project being in your native country?

I've never understood why non-holders take such an active interest in incessantly bagging companies when they do not have a direct interest.

Seems like such a waste of one's time.

Does "I told you so!" also apply to shares you hold?

For instance, I have zero interest in what happens with AVZ as I am not a holder but I have zero interest to go on those threads preaching my opinions but for the sake of all holders there I do hope they can sort something out.
