Yep. Algorithms and paying for placements.I know its something to do with the algorithms. I remember reading an article about it a while ago. Sky News gets more significantly clicks with news reports on YouTube than the actual Sky News channel as their news clips always appear at the top of peoples recommendation lists.
The likely same applies to Twitter going by the way Elon skews his algorithms and overseas based RW bots.
It is far from any type of balanced business model.
