Admitting it was bad and reversing it is (usually) better than just letting the original bad decision stand, but you can't erase what you've done. You still publicly decided to do something that caused people to lose trust and faith in you. People will wonder if you're going to make other bad decisions, and then not walk them back when people tell you how bad those decisions are.

There are also good and bad ways to apologize and change your mind. I don't have an opinion as to whether or not Docker's apology and reversal were done well, but I think it's fair that some could believe they weren't.
