Yes, but why does it matter if China intercepts your American school children? Why would they want to? That's not a reasonable threat model.
"Someone", sure, but not the Chinese Government! That's a completely different threat model!
The Chinese government is the last entity I'd be worried about with this kind of information (unless, of course, you live in China). Certain criminals in your own country are a much bigger concern.
This is similar to the concern some of us had over giving local government departments access to our full Opal card public transport travel histories here in Australia. Not all government employees are up to no good, but some are. Don't give them more than they need.
See their push into universities.
Because China=bad, Google or Facebook or Microsoft (which all provide data to) or NSA =good
