Why does Trimet insist on lying to the riders about MAX delays

For a short while there it started looking like Trimet officials (twitter) were actually telling people the truth about MAX delays. Now all of a sudden they are back with their same old bullshit

The original tweet

MAX Green and Yellow lines are delayed by about 20 minutes through 6:30 p.m. due to a mechanical issue.

The truth of what is happening. And they know its the truth but they don't tell people what's really going on!

@trimet more like 45+ min ... at least on the Green line #trimetfail

@trimet 20 minutes is tolerable, but 50+ min is miserable in this heat .. 😒

Don't understand @trimet ... Green line spsd 2 arrive Gtwy 5:08, arrives 5:53 ... #Trimetfail calls it 20 min late ... Looks like 45 2 me

@trimet 20 minutes is grossly underestimated.

6th max and we finally get on means 1 hour waiting for the blue line. @trimet when are you adding more?
