This isn't accurate; they've been separate companies for years now. It's kind of a winding history but the TLDR is TripAdvisor started out as an independent startup. Was purchased by a large holding company, which also owned the Expedia brand (acquired from Microsoft). They then mashed all their travel companies together and spun the resulting behemoth out as "Expedia". A little later, Expedia split TripAdvisor back off into an independent company once again so it could focus on being an OTA. So it's true they were linked at one time, but that's no longer the case. They're distinct businesses with no formal connection. (Disclosure: I work for TripAdvisor as an engineer, though I wasn't present when all of that went on)
