> No school is going to compete on the basis of "we don't use Google services (we pay for more-private infrastructure)"Um, what? Didn't you just get through saying you don't want your kids to have to have Google accounts just to go to school? Do you think you're the only parent who wants that? Isn't the protection of your kids' privacy by the school worth something?
If you're unwilling to pay anything more than zero for something you claim you value, then your claim that you value it becomes, to say the least, questionable.
> if I'm a parent of a school-age child, what exactly do you think I should do?
You mentioned homeschooling yourself. In our current environment, unless you are very lucky in what school district you happen to live in, that is probably the only option to avoid giving up your kids' privacy.
> don't have any right to expect our data to be private
Google apparently doesn't think so, and neither do your kids' current schools (and I suspect your implication that the vast majority of schools in the country are similar is correct), which means the government that runs those schools doesn't think so either.
> Sometimes the only way to crack collective action problems is government intervention.
No, that's my point: governments do not solve collective action problems. They grab power using the excuse that they are going to solve such problems Real Soon Now, but they never actually do. Governments run all the public schools in this country: they have had all the tools they need to solve the collective action problem of how to protect kids' privacy in a digital world for quite some time now. And they don't care. And this is just one of many, many examples.
