All that being said, I find it a little odd that this article is somehow decrying HAOS as a worse alternative to a proprietary, anti-user black box developed by companies trying to squeeze more profit, just because they played fast-and-loose with some shell scripts at some point. (Aside: I just installed Homebrew on a new Mac today, and it's still just a curl | sh)
Most of the major consumer IoT vendors have had major security incidents (Wyze, Hue, Nest, Arlo, many others), and if nothing else, my little HAOS Rpi gets a little obscurity compared to the big names getting hit by script kiddies. Not to mention it's easy for me to keep it local-only and just join it to my Tailscale network.
But given all the allusions to HomeKit, I suspect the author has total faith in Apple to do it right (not a wholly misplaced assumption) and wants everything to just talk HomeKit.
Which we might actually get (in practice) as Matter makes inroads! Hell, I'd love for everything to talk HomeKit because HA can emulate a HomeKit Controller, and that means less cloud APIs. Win for everyone!
