I’m guessing this is in reference to a recent YT video about private equity buying up YouTube channels in recent years, mostly in the science and engineering spaces.

Channels publicly acquired by PE:

Task & Purpose, Donut Media, Veritasium, Simple History, Fern, Fireship, Economics Explained, Futurism, Astrum

“Your favorite YouTube channel is (probably) owned by private equity.”
