So many possible reason.
Linus has a history of scummy behavior which turns people off.
Everything gets boring eventually. Especially things that are supposed to be funny.
Google ads are extra obnoxious making the entire platform more annoying to use and most of us will never pay for youtube. Those ads are not even selling products I would be interested in. Investment scams, car accident claim ads, AI voiced robot panda. It just annoying noise.
Nothing lasts forever.
The only healthy option here is water.
All the other options contribute to obesity. Lots of calories.
I remember having a discussion with a lady that was upset that they removed soda and juice from the vending machines at school. She claimed that juice was healthy. I told her that the problem was that all the kids are fat not that they’re low on vitamin C which is very easy to get from other foods.
