Have you ever heard of an independent car repair shop being allowed access to the manufacturer’s factory floor ? How about factory floors of all car manufacturers? It makes no sense. How about I go use your home’s toilet when I’m nearby?
Remember the days when you had to pay per text message?
Car manufacturers used to publish detailed (technical) manuals for all of their cars exactly so mechanics (owners, repair shops, etc) could work on their vehicles.
In modern times though, manufacturers seem to be DRM-ing (and similar) as much as they can in order to capture the repair business for themselves. It's not a good look. :(
If a niche enthusiast crowd worth of traffic will absolutely obliterate the underlying infrastructure, allow unchecked flows of spam and undermine the security posture, maybe Apple should just leave it to the telcos who might be marginally more competent.
