I don't think many children work in tech... but anyway VPNs are used by any industries.
That being said, my non-expert reading of the amendment [1] is that it only applies to "consumers", which someone using a VPN for business purposes is not:
> “consumer” means a person acting otherwise than in the course of a business;
> “relevant VPN service” means a service of providing, in the course of a business, to a consumer, a virtual private network for accessing the internet;
