Honestly I have no idea what to make of it.

In my mind it could be:

1) Simple copycat - article author is watching predictive history which seems plausible given channels surge in popularity

2) Algo effects

3) Coincidence / think of pink elephant effect

4) An actual coordinated intentional campaign by [insert evildoer with insert evildoer motive here...or even 3 letter agency meaning well but ending up functionally doing same as evildoer]

...the fact that I couldn't tell #4 apart from 1-3 has me a little spooked
