I would point you to the Clubs beta and now rollout as a great example of how Zwift listened to feedback and made changes quickly and communicated effectively. Beta Feedback Recap & January Update
While I share some of your frustrations about the speed of development, ignoring bugs until it’s too late (ios crash at the top of the alpe), lack of communication and miscommunication, I don’t think it is fair to say no one at Zwift listens or cares and nothing gets done. The last few months I’ve seen a huge shift in forum posts leading to action thanks to @James_Zwift and @Eddy_Lee.
