You really wanna be scared? Go look at the multiple comments on the EU DMA announcement complaining that having a sideloading option is just a ploy for malware vendors to get into their iPhones. Or that someone else being able to sideload or jailbreak somehow hurts their security. These are coming from actual HN users!
Was it voted so high it triggered some bot detection? That would only explain the former, not the latter. Either way, there's something funny going on.
