Why would better technology make it easier for imperialism to spread?

Quick answer. Technology would make it easier for imperialism to spread because negative social media is possible. The internet is very big, and not everyone has the same opinion. As you know, North Korea is a communist country. The leader, Kim, could go on Twitter, and tweet about imperialism, and he would get a bunch of supporters because this world will allow it.
