Waymo maybe could have gone with Lyft (or built their own app) if the deal with Uber fell through, which is probably why Uber accepted it. It's not "help Waymo get to market or not," it's "help Waymo get to market or risk somebody else (or Waymo themselves) passing on Waymo's value to customers and taking the market." Especially with the chance that Uber might get to play gatekeeper in the future, it's a hard deal to turn down.
