Agreed. But this isn't about disclosing a conflict of interest; this is about the creation of a federal regulation that is both vague and unnecessary.
Why is is challenging for a blogger to disclose that his "review" was preceded by a payment from the company whose product he is reviewing?
As I stated earlier, it's a hurdle just to become familiar with the regulations that exist and confirm that you are in compliance. Imagine that a person doesn't blog today but wants to get into it - that person may be deterred by knowing that there is a world of federal regulation out there that they don't understand.
