Is this plugin just for sites with ads on various platforms?

I’ve set up this plugin for Google Shopping.

However, I see in the plugin description that it also produces product feeds for “Facebook Product Ads, Bing Ads, eBay, Amazon, etc”.

<b>If I understand correctly, the product feed is only of use to a WooCommerce user if they use ads on these various platforms.</b>

So if my client happens to sell on eBay, but he’s not actually buying eBay ads, then it serves no purpose for him to generate a product feed for eBay. Is my understanding correct?
