There is also another issue. This time legal.

Sometime in country X something is prohibited. Can be online casino, can be social network, etc.
So court there prohibit site X to be viewed from country.

And fun starts here IF you share IP with one of these blocked IPs.

Example:https://www.theguardian.com/world/2014/mar/27/google-youtube-ban-turkey-erdogan

Since YT share IPs with GC some sites getting blocked in Turkey.
