This happens more often than you would think.

During COVID, lots of live shows (concerts, etc.) in Japan moved to streaming (and most of them stuck, so thanks to that, lots of large concerts today have real-time streaming, which is great for foreign fans).

Out of 10+ platforms, more than half have vulnerabilities that allow you to access the content freely (sometimes including the rehearsals, because they are also streamed internally), and on a handful, you can access the admin panel and, as the author said, stream whatever you want.

Most of them have been patched over the years (some are just the byproduct of them changing the backend/SaaS provider, though), but there remain some major providers where you can get content for free.
