So I think I largely understand your point. But I am genuinely curious to know how you would then get information about products.

Would it be on-demand research only? Would you browse lists of new products [eg the Wirecutter's "Realist guide to CES"]?

I do both of these already, and I do have js disabled on most sites, and I think ads mis-align the incentives of publishers...

But I think that there are demographics that benefit from ad-supported [ie free] stuff more than I do.
