Have you actually done this approach? If so, I'd love to hear more.

I ask because I often see the advice that people should look in the Shopify/Hubspot app stores for paid apps with lots of users/ratings and a low score, and while this sounds good, I've found very, very few apps that actually match these criteria. Typically a low score indicates a complaint that is outside of the technical scope that the app owners could address, and ends up being a weak signal imo.
