I read it more as, if your kid is intent on something, rather than slap them down, try and work with them to turn it into a positive experience.
Most kids adore doing stuff with their parents. It lets them practice adult skills, with the safety net of a trusted adult behind them.
With something like streaming, it would be down to the parent to keep them safe and let them explore their creativity. It sounds like this dad screwed that up, but is trying to at least own his part of that.
There are nuances between feral parenting and helicopter parenting.
