I mean, because the world is connected via a large global network with instant communication.

It's kind of like asking "Why did the world kind of destabilize politically during the 1910s". Massive technological change swept the world and fast travel changed the dynamics of the world.

Our world has changed from one of bulky analog data (paperwork, pictures, remote places) to one where any information can be digitized and sent anywhere in the past 2 decades. This data can be stored pretty much forever. This is as much of a change as what occurred in WWI and WWII. The political dynamics of the world are completely different in the data regime. He who controls the data controls the world.

This is a very difficult trend to counter, just because you decide not to control said data, doesn't mean that others aren't capturing that same data and using it against you, in which they'll take power.

There is a distinct possibility that rights and ever growing capabilities of technology are fundamentally incompatible. This is going to present a growing problem for human societies.
