It's the fault of customers also. Many are knowingly not giving their choice & many are not aware about all this.
Once DPOs will start discontinuing the channels, all will give their choice in one day.
It's not fault, it's human behaviour. Don't fixed it unless broken. So unless they face discontinuation on TV, nobody bother about wasting time on these petty issue like calling operator when they have much bigger issue in daily life to think about.
BTW now for TS only issue for them is now that they failed to get stay order from any TRAI action from Delhi HC, So after Sony blackout it seems TS users will get total blackout
