@matt_teachmaths @aus_teach While I agree with Simon, having been a tech director, I can appreciate how tough it is to put policies in place that allow for free flow of information. Some schools and systems desire a "walled garden" approach to education. What's inside the garden is considered safe, and any tech that opens a hole in that firewall is to be banned.
The Fediverse suite of tools, unless it can be closed and locked down, is anathema to many school systems. And, with radical/extreme conservative views on the rise (speaking of USA, not sure of anywhere else), anything that doesn't toe the line of evangelical values will come under fire...whether it merits it or not.
As a result, no school administrator will brave the fire to rethink digital practices to be more open.
