I agree with this for the following reason
I have worked with children of different age groups, if you take platforms such as repl.it then one of the main features is to allow collaboration.
So as a code club we have access to repl.it, access to coding language and the ability for them to help and support each other in projects.
This encourages skills such as communication and collaboration
In terms of age limits on platforms, you can have a 10 year old who can be responsible and mature enough to use the platform properly but under coppa probably can't sigh up, you can have a person 13+ who can sign up but some people age 13+ can act like idiots, and vice versa on this.
If we want to encourage the next generation to code and learn these skills then they need access to the same tools as others to do that, as adults we need to make it clear what the expectations and parents need to take responsibility for their children and not see these online tools as a child minding service.
