What? The only thing with any definitiveness in what you linked is that 72% of teachers are using an outdated method for teaching early level reading skills (letter and word recognition).
As a secondary point, it says that teachers feel their kids can’t read anymore so the teachers have taken to tiktok about it.
There’s nothing there indicating high levels of illiteracy, or that they’ve been caused by an over use of devices as babysitters, dawg.
I think you need to brush up on your literacy.
It sure as hell isn’t a good thing, and it isn’t helping kids read or develop, but this is the same argument that’s as old as fucking time itself where older adults blame new technology for degeneration of the youth. People literally made the same complaint about radio dramas leading the youth astray.
The core of the issue is that it has become increasingly easy for parents to use technology to avoid properly taking care of their damn kids.
