Not that I'm aware of. But I do know others in the industry have changed their minds, like for instance RocketLab. Peter Beck, who said that if they ever were going to make a reusable rocket he'd eat his hat, actually did announce a reusable rocket and later did actually eat (part of) his hat: https://www.youtube.com/watch?v=agqxJw5ISdk&t=188s

(Love that he actually did it haha!)

Yup, I’m a fan although disappointed they have only announced the testbed instead of an orbital rocket.
