*The shift to online schooling is running roughshod over children's privacy rules and rights,* which were inadequate to start with.

The article is concerned that wealthier schools will choose systems that "protect" privacy "better" whereas impecunious schools will have to use systems that protect privacy less. That would be a real danger, if some of these systems did protect privacy.

In practice, none of these systems give much protection. Whatever data a company collects is already on the road to being misused. The only effective protection for privacy is not to put the data in a database.
