It's a dick move from Google abusing their power to enforce what they think is good for students. On the other hand it takes away some of the control schools have over them. That's a good thing when a lot of kids come from controlling families where school is the only escape.
It might also help everyone realize that graded homework is a waste of time. Grades should come from tests that are so hard you can only pass if you really understand the material. If someone needs practice they will know it and do the homework they passed on. Have a computer room where anyone can come and do any test they want, unlimited retakes and no time gates. Fast learners can skip ahead, everyone else gets the chance to practice and try again until they get it.
