Professional reviewers already find out directly fron the product creators. They want to be contacted by them and even seek out contact. This problem is already solved. In general, they certainly don't learn about products from advertising.

>How do I know they aren't receiving products for free or more subtly being specific in what products they will or won't review in order to spin a narrative. I'm a big fan of good product reviews but this doesn't solve advertisings problems it just introduces new ones.

I generally don't have a problem with professional reviewers recieving products for free to review them. If they get paid to push a certain product, while pretending they are a neutral source of information, I would consider this fraud.

>What solution do you envisage to the problem of ads as you see it? to ban them entirely?

Yes, I advocate banning advertising and I hope to contribute to support to put that measure into place.
