lol they're going to backflip on YouTube, so now Google is Big Mad, and the Coalition is rubbing their face in it from the sidelines (while not taking a position themselves) and Snapchat and TikTok are all going to be yelling about YouTube and this is all such an obvious mess that was predicted in advance by many people.
And yet the beans will continue to be vigorously inserted.

It has weird things in it, like "some messaging services include features and functionality associated with these harms, such as ephemeral content that is only accessible for a short window of time"

You are describing a phonecall.

"recent findings from the Black Dog Institute showed an association between higher daily hours spent using YouTube and greater symptoms of depression, anxiety, and insomnia."

correlation != causation. Deeply unserious stuff here.

"In general, I caution against excluding particular services without conditions in the Rules. A legislative instrument excluding a particular service would be based on a point-in-time assessment of that service."

Yes, that is the entire purpose of a legislative instrument. It is to enable point-in-time assessments to be made by the Minister, and a new legislative instrument to be issued. It means you don't have to go back to Parliament for a new Bill for an Act every five seconds.

But otherwise, sure, feel free to accurately and completely define the behaviour you are trying to regulate such that we can all objective determine if a given service is in scope or out of scope. It will save us a lot of court cases trying to figure out what Parliament meant by "the vibes are off".

@daedalus Writing down what they mean could lead to accountability* and people meanly pointing out that you don't know what the hell you're doing.

*OK, to Australian levels
