Why are the top animes, such as OPM/TBATE/BlueLock-S2, and Seven Deadly Sins, being pressured by poorly-Studios that have bad production efforts?

B_tch ahh studios such as :
- Studio-A Cat (Ruined TBATE's adaptation)
- L.C Staff (****** up OPM to OFM)
- Studio Trigger (Trash idc)
- Studio-Sunrise (Cornball animes, wrap it up)
