Australian here. I hope Apple etc.do just walk away. Our government has been a continual embarrassment for a decade now and they're just getting worse. Until they start getting reality checks they'll just continue pulling stupid stunts like this.
This is a dumb, untenable, largely unenforceable and pointless law.
Even if Apple were to start delaying product releases in Australia by six months to do "legislative compliance reviews" or some such. With telcos on-board, this might encourage our politicians to listen to actual experts when touting this kind of legislation.
The stupidy here crosses the isle.
