You see those complaints as reasonable? I would have wanted the teachers, instead of complaining, to start by apologizing to their current and former students: "We taught you badly, we mangled many of your peers' ability to read, we wasted your time and failed you - we are so sorry! We had good intentions but we didn't know better, we were ordered to follow a plan, and we didn't bother to stop and think if what we were doing made sense."

But instead of acknowledging that they had been setting up children for failure and taking immediate action to improve things, they are dragging feet and complaining about "district leaders needing time to make instructional plans". As if their school and district are unique snowflakes, and nobody else in the country had published good enough plans already.
