MOMOLAND had a good run, MLD wasn't able to capitalise on their success with 'Bboom Bboom' and decided to basically repackage & re-release it as 'Baam' which essentially doubled down to secure them as a one hit wonder which was quite possibly the worst decision any company could've made short of disbanding the group or putting them on hiatus.
I don't follow or know much about TFN so I can't comment on them, and Lapillus seems to be having major success in the Philippines which is nice. However, Lapillus having a lot of success in the Phillippines probably isn't the best thing because the Filipino music market is even smaller than the Czech music market (a country 1/10th the size of the Philippines) which is a very bad business strategy on MLD's part.
