Third-party JavaScript is easy to add and often reduces accessibility and performance — it injects DOM the site owner never reviewed and adds load time. "Pages w/ finding" is the share of pages carrying this vendor that also had an accessibility finding: an association to investigate, not proof the vendor caused it. Third parties vary per page, so a vendor on few pages may simply not have been sampled elsewhere.
