Also PBS has a great kids games app(s) that are free with games that are fun / no ads.
And PBS kids video app is again free, great content, no ads.
If you're in the US and care about that content, I suggest contributing to your local station. The quality of the content from kids to adult is outstanding. It's not usual for me to browse a few streaming services and just end up watching PBS's content in the end.
Maybe when it comes to the article they mean more accessible? But I'm not sure as they seem to ignore the PBS content available.
