'Big creators' seems to be fairly ambiguous. I've seen plenty of sponsorship segments on <10,000 subscriber accounts, which (I'm guessing) is probably the threshold where the creator is starting to make noticeable money from Youtube, but not quite enough to go full time. It's the big creators who seem to not have the sponsorship segments in my experience, because they have enough income from other parts of their brand.

People use adblock now, I don't see how this is much worse. In my opinion, this is more ethical than adblock since it allows easy whitelisting and has an easy to click unskip button.

Web ads generally come with tracking software baked in. Paid sponsorships do not.

Most of the "Big creators" I see rolling sponsorships on youtube are nowhere near even the size of even smallest of creators on cable tv.

Many of them are literally one to three people with a camera.

I’ve seen channels with as few as 10,000 subscribers have sponsors. This is literally screwing with some person’s job.
