We used it as a teacher.
If you have a student who won't graduate, you bring in the parents and say.
"Johnny here only has 12 credits through his first three years of school. So, he can't graduate if he stays with us at his local high school. But, if you sign these two papers, we can withdraw him from our high school and enroll him in the online charter school where he can earn all the credits he needs to graduate by working at his own pace online and graduate this year."
We would do a LOT of this in September and January (and again March when it sunk in the kid wouldn't graduate) of senior year. The catch, all money for the kid for the entire school year went to the Devos family owned charter school even if you did this in May of senior year.
We did this with about 10 percent of our senior class every year. We had a 96% percent graduation rate this way. We literally never had a kid ho the online charter and get a diploma...but the charter schools don't have to report graduation rates.(they do provide profit/loss statement to investors).
Didn't read the article, because I know how the sausage is made. Because for twenty years I was in the room where it happened.
(Fyi .. our district actually planned on that loss of revenue when budgeting)
