The YouTube video seems to indicate that even if the company didn’t pay but provided the product for free, you’re supposed to check the box.
my understanding of the FTC's rules is that you need to clearly disclose when you get something of value, whether cash or a product. They don't specify what form that disclosure should take, so either verbal at the beginning of the segment or checking that box is fine.
I agree, and that's why I rarely check the box. I prefer to say very clearly what the relationship is at the beginning of the video. I checked the box for my 4 hour desk build stream cause I figured people would be dropping in and out and might not hear my initial disclosure
