This has been something both requested and discussed online for a long time. Kids can't really decide what information to share and what not, and they are often bombarded by retargeting ads supported by analytics services. It still remains unclear how those apps will make money using 3rd party ads, but it is clear that kids apps won't be able to use 3rd party SaaS services (Mixpanel, Amplitude, Firebase, etc) and have to rely on same-domain-on-premises and/or open source product analytics services, eg Countly (shameless plug: I am co-founder of Countly, building an open source analytics platform particularly for privacy and security reasons). Let's see how it goes. Apple sometimes comes up with a "quick" decision and then stands down after a few months as criticisms occur. I expect that corresponding wording will change until the section goes into effect.
