Wonder if it even matters, as when we bought our house ~12 years ago, we used Redfin as our buying agent, and, even though we had a real realtor working for us through them, the selling agents were super defensive and refused to deal with her. They would only deal with us directly and we'd have to forward info to her, etc. First home so had no idea how this was supposed to work, but seemed other real estate agents didn't treat Redfin as a "real" realtor in any case.
