Coincidences of Train Issues??

Is it a coincidence that out of the 2 train service providers in Singapore, only SMRT

1. has problems with their train doors opening mysteriously by themselves;
2. has problems with regulating the air-con of their trains (sometimes being very stuffy);
3. has problems with telco reception in their tunnels (except Circle Line);
4. has problems with irregular train schedule (granted that NEL is fully automated); and
5. thinks that we have bionic eyes and only cater one LCD screen per platform to display the train arrival?

It certainly seems so. In fact, I think SMRT is more interested in opening retail shops in the MRT stations then improving their service levels for their bread and butter, train service.
