That hasn't happened because they're cheap, effective, and relatively easy to manage. Unless Google fucks things up big time, they're probably going to be around for a long time.
I'm 100% in favor of people going directly to teachers, principals, counselors, on and on up until enough additional busywork is piled on top of these civil servants that their choice is a perpetual drowning in outrage or a removal of abusive technology.
It shouldn't be that hard to accomplish; possibly even just ten to fifteen people per school, applying pressure wisely, ought to make for effective burnout.
