Personally, I don't understand why Lee Soo-man hasn't been jailed for breach of trust and economic crimes.

The most famous recent case was the issue regarding Min Hee-jin and ADOR's breach of trust, but Lee Soo-man's case seems like an even more definitive breach of trust.
I had heard a bit about the issues with Lee Soo-man's Like Planning, but I didn't realize it was this serious.
Since the 2000s, Like Planning has been a company 100% owned by Lee Soo-man, providing advisory contracts for overall producing...
He started by contracting it at a level of receiving a portion of album sales revenue, but later, he was taking up to 6% of SM's total revenue.
This means that even if SM incurs a loss, Lee Soo-man continues to receive money personally.
Looking at the 2020 figures, SM's separate income statement showed revenue of 300 billion KRW and an operating profit of 36.2 billion KRW, while Like Planning took 12.9 billion KRW.
As a result, the money Lee Soo-man received separately through Like Planning exceeded 150 billion KRW as of 2022.
The work Like Planning does is advisory on overall producing....
A person acting as the CEO inserted advisory contracts for tasks he was originally supposed to perform in order to secure personal profit.
I know that SM shareholders have been seething over this, along with Lee Soo-man's per-performance fees,
but I don't understand how no one has filed a lawsuit for breach of trust, or why the financial and investigative authorities have just stood by and watched.
I truly didn't realize it was this serious.
