This is my speculations only:
Since BTS renewed in 2018 and it was reported to be for 7 more years. The timeline is strange. 7 years from 2018 is around 2024 but their original contract didn't expire until 2020. So either reports were wrong and BTS renewed for a shorter amount of time or there was contract renegotiations that has led to HYBE cutting their nose to spite themselves and not supporting BTS anymore. This started after 2020 (IMO).
I just hope that BTS leaves HYBE because they could start their own label or get a sublabel with UMG. To build a company from near zero to a billion dollar company is quite a feat.
