No, mainstream media is part of capitalism.
Specifically shitty mainstream media (I'm sure there are some mainstream media providers that aren't shitty).

This is a shitty product.
This is a shitty product that is part of capitalism.
This is a shitty product that is part of capitalism which happens to show mainstream media.

But this isn't mainstream media.

Mainstream media would want in on the ad revenue. Mainstream media would facilitate & encourage this.

This is just a shitty product from a shitty company capitalising on shitty practices.

Edit:
I guess "part of the same bullshit" is correct.
But it's placing the blame on the wrong thing

Mainstream media is just media consumed by the majority of people.

It has nothing to do with money.

But capitalism tends to rot anything it touches.
