Whats sad is it doesn’t even take much knowledge of technology to know the whole of Sunbirds “product” was a terrible idea even outside of security concerns.
“Hey! I’ve got a brilliant idea for a product that absolutely could not fail!, lets reverse engineer one of the prime services of one of the most protectionist and litigious companies in the world and publicly advertise and try to sell it to their competition and potential users as some sort of magic compatibility layer”! What could possibly go wrong?
It was a worse idea than Dolphin thinking they were going to get away with trying to monetize their Nintendo emulator.
EDIT: I was mistaken about Dolphin looking to charge for their emulator when they put it up on Steam, as pointed out by a few folks in the comments. They were just looking to distribute it on the platform. Still seems like wishful thinking to me though when talking about something related to Nintendo and IP.
Good
It was a pretty bad idea, not only a privacy risk for users but for anyone those users interact with. You no longer get the guarantee that your iMessages are end to end encrypted since anyone using the service puts a man in the middle for everyone they communicate with.
