The PD changed since then. The PD at the time was Sohn Suk-hee who also was the anchor (has a big reputation in Korea). He stepped down in December 2019 shortly after the BTS scandal (though has not been reported it was because of that), and later was JTBC's President for some time in 2020. He made his return this year with a show on MBC.
BTS just has an unfortunate position in the korean media landscape in general and beyond. Heck there was even a Korean rail employee who was fired for accessing RM's personal info but quickly got reinstated. I remember a similar issue with BTS's members being followed when they received covid-19 vaccinations, and Jin supposedly had somebody in the military following him too at his doctor's appointments. The 'fairness' argument that people always talk about when it comes to BTS's enlistment or even now with Suga's case is not reciprocated when BTS are the victim of something. Somehow a lot is acceptable then. It's something you see in celebrity culture in general, not just in kpop or with BTS. Shows the limit of all of us in that we demand celebrities to behave in a certain way that we ourselves cannot even adhere to.
