People aren't bored, but the economics have changed in terms of ad revenue, and the notion of linkbait has been tragedy-of-the-commonsed since everyone is doing it.
Or everyone else is just stealing the playbook, and consumers really don't care where the content comes from.
Readers of clickbait presumably get to such pages from social shares aimed to grab a click, and probably have no loyalty to the site producing the clickbait.

I think that's spot on. There's more competition in clickbait and the strategy ultimately doesn't result in any sort of loyalty. They are there for the headline, quickly consume what little content there is and close the tab.
It's a process of finding a new "weird trick" and then overuse it until people get sick of seeing it. Then find a new hook and repeat the process ad infinitum.
