The line is descriptive: it does not establish product substitutability, competition, common ownership, causation, or a legally defined antitrust market. The 2017 and 2022 graphs use the exact same strict-match rows with every selected lens measure and both plotted axes published in both vintages. Added and removed mean only that a reciprocal top-three fingerprint threshold changed.
