A no ads typing program: I had to look over my kid's shoulder to realize this even mattered

My kid was using some online learning thing that was supposedly educational and when I glanced over there were ads in the sidebar, a notification badge trying to sell an upgrade, and a little cartoon character trying to get them to share something to social media. On a platform marketed to elementary age kids.

I want to say this surprised me but honestly the "free" edtech space has always been a bit like this. The product is the kid's attention and the parents are just along for the ride. Seeing it in action on something I'd okayed specifically for educational use felt different though.

Has anyone done a real audit of what their kids are seeing on the platforms they use daily? And have you found alternatives that are actually clean without being stripped down to the point of being useless?
