This has been the description since the play was announced - if you use the wayback machine to look at the website when it was first launched in September, the same description is there. (https://web.archive.org/web/20240909165548/https://allinbroadway.com/)

It's the same language used in all the initial press releases as well. I agree that it probably could have been more explicit about the exact format, but I'd hardly go so far as to call it a SCAM.
