People tend to choose the best way to get more likes and become more youtube famous. The problem is that in most cases they end up loosing the feel and purpose of their channel becoming just like-hungry.

Exactly. The "thing" they do bring them a lot of subscribers and views so they become reluctant to change the way they do their videos. And in a way that isn't so strange: Why change when what you do bring you a lot of views? Of course it's bad for the channels in the long run since they'll run out of content but it's not easy to change and maintain as many of your followers as possible.
