It may not be a perfect driving solution (probably 1:1 teleoperator to car in the beginning), but their go to market speed is undeniably better than Waymo et al. Waymo, Cruise, etc have to map out an entire region and have long rollout timelines. In theory Tesla could say they will deploy in X city, talk with the local government to get necessary approvals, and get it going after a few test drives. Thats the tail, anyway. With that kind of go to market speed you can start acquiring customers pretty easily and start scaling up the business. Its basically the typical SaaS setup - cut some corners for market share and become the defacto player in it after some time.
I wouldn't write them out purely out of spite. Their solution is the most conducive to scaling laws, on the ML, operations, and business side.
